Update group memberships when entity is deleted (#5786) 

* Use common abstraction for entity deletion

* Update group memberships before deleting entity

* Added test

* Fix return statements

* Update comment

* Cleanup member entity IDs while loading groups

* Added test to ensure that upgrade happens properly

* Ensure that the group gets persisted if upgrade code modifies it
