Removing AdminSet manager does not update edit_access in solr doc

[elrayle]

Descriptive summary

When a user is removed as manger of an AdminSet via the UI, the user is not removed from the edit_access_person_ssim in the solr doc. (Likely the same is true for group managers.)

Expected behavior

When a manager is removed, the edit_access_person/group_ssim in the solr doc for the AdminSet should have the user's id removed.

Actual behavior

When a manager is removed, the edit_access_person_ssim is unchanged.

Steps to reproduce the behavior

Prerequisite:

1. Create 1 admin user and 1 non-admin user
2. Create an Admin Set
3. Login as an admin user
4. Create an Admin Set and Save
5. Add non-admin user as a manager
6. Click the Participants tab
7. Add Participants -> Add user: -> set to non-admin user
8. Set role to Manager
9. Click Add button
10. VERIFY: Check solr document for the new Admin Set in Solr and verify that the selected user is in the edit_access_person_ssim list.

Reproduce the issue

1. Remove the user as manager
2. From the Participants tab, click the Remove button next to the non-admin user just added
3. NOTICE: Check solr document for the Admin Set in Solr and notice that the selected user is still in the edit_access_person_ssim list.

EXPECTED: I would expect the edit_access_person_ssim to no longer include the removed manager.

@elrayle were you testing before or after this was merged? #567

I took the latest this morning. I still see the described behavior.

@elrayle thanks for checking. I'll have a look.
