Cannot Query Field with handle author via GraphQL (Internal Server Error)

[reilnuud]

Description

Created an entry field with the handle author on a channel entry type. Kept getting an internal server error. Changed the handle to authors and it worked. It looks like Craft is trying to lookup the User who created the entry rather than the field, but gets confused doing so.

If the underlying problem cannot be resolved without significant refactoring, my recommendation would be to add author to the list of reserved words.

Steps to reproduce

1. Create an entry field type on an an entry with the handle author.
2. Query the entry field with GraphQL.
3. Get Internal Server Error resposne.

This is a duplicate of #2797

Unfortunately, it's not possible to use getFieldValue() in GraphQL, so you definitely won't be able to use an author custom field on entries in GraphQL until #1524 gets resolved.

For posterity, this is resolved for Craft 3.7.
