Problem with permissions for editing models

[appukuttan-shailesh]

When I try to access a public model with my test account (no admin privileges), the “Edit” button is still active. It doesn’t let me save the changes (I get a message saying I’m not a member of the collab), but it would be better if the pencil icon wasn’t shown.

Currently the only check for "edit" (pencil icon) it so see if the model or test instance is editable (no results linked to them), and there is no user based checks.

@apdavison might implemenet a new endpoint in the API for checking access.
Awaiting above end-point before proceeding on this task.

The same end-point could probably help handle #262 as well.

This has been implemented.
