[1.8.x] Refs #24225 -- Added failing test case for removing a previously
added field in migrations
When a related field is deleted, the related model must be updated. As
unchanged models are shared in migration states, the related model must
be re-rendered so that the change applies to a new copy of the related
model.
Thanks Henrik Heimbuerger for the report.
Backport of 58d0dd9260156067263ea7a2da2685c3cd88e18a from master
