Batch add works to collection from collection admin show page when all fail doesn't forward as expected

[elrayle]

Descriptive summary

This issue lays out expected forwarding behavior when adding works to a collection through Dashboard->Collections->collection show page fails for all works.

NOTE: This likely uses the same forwarding behavior as adding works to a collection through Dashboard ->Works. This issue and issue #4006 are tightly related and the fix for one may fix both.

Rationale

Provide intuitive forwarding behavior that focuses on the actions a user will most likely want to take next. Provide error message that is easy to understand.

Expected behavior

When adding multiple works to a collection from Dashboard -> Collections -> collection show page...

FAILURE to add any of the works should:

• forward to collection's admin show page
• shows flash error (red): Collections Error: You have attempted to add works to more than one collection of the same single-membership collection type (collection type: name of collection type, collections: list of effected collections). None of the works were added.

Testing

• Need to update specs added in PR fix single membership and add single/multi-membership spec tests #2687 to match the forwards described in this issue.

Actual behavior

When adding multiple works to a collection from Dashboard -> Collections -> collection show page...

FAILURE of all works added:

• forwards to collection index page Managed Collections tab (if user has managed collections) or Your Collections (if user does not have managed collections)
• shows flash warning (yellow): Collections Error: You have specified more than one of the same single-membership collection type (type: name of collection type, collections: list of effected collections)

Steps to reproduce the behavior

Prerequisites:

Need a collection type that is set to allow single membership. If testing on Nurax, this collection type may already exist. Look for Collection Type Single Membership. If it doesn't exist, then create a single membership collection type using...

• Dashboard -> Settings -> Collection Types -> Create new collection type
• Assign type name Single Membership and Save
• On Settings tab, uncheck MULTIPLE MEMBERSHIP and Save changes

Need two collections of type Single Membership. You can create using...

• Dashboard -> Collections -> New Collection -> select Single Membership type -> Create Collection
• Assign suitable titles for the two collections and save. This issue will refer to them as SM1 and SM2.

Create 2 works and add to collection SM1 using...

• Dashboard -> Works -> Add new work -> fill in requirements -> Save. This issue will refer to them as Work1 and Work2
• Dashboard -> Works -> check box beside Work1 and Work2 -> Add to Collection -> select SM1 -> Save changes

Test:

Verify FAILURE to add works to second collection of the same Single Membership type.

1. Dashboard -> Collections -> click title for collection SM2 -> click button Add existing works to this collection >>
2. check box beside Work1 and Work2 -> Add to Collection -> Save changes

Verify forwards to SM2 admin show page. (Admin show page is the show page for the collection with the admin menu on the left.)

Verify flash error (red) with message "Collections Error: You have attempted to add works to more than one collection of the same single-membership collection type (collection type: Single Membership, collections: SM1, SM2). None of the works were added."
