[PM-24055] - Collection Users and Groups null on Public response (#6713)

* Integration test around getting and saving collection with group/user permissions

* This adds groups to the collections returned.

* Added new stored procedures so we don't accidentally wipe out access due to null parameters.

* wrapping all calls in transaction in the event that there is an error.
