Description

When there are various database ops in SeparateDatabaseAndState, and they depend on each other, database_backwards is broken because it applies states incorrectly.
The code exists unchanged in 1.9 and master.
Test coverage for SeparateDatabaseAndState was incomplete anyway, added a more thorough test which breaks, and the bug fix.

Refs #25896 -- Fixed migration test failure on Oracle

The test creates and deletes a model in the same migration, and the model
had an AutoField. On Oracle, AutoField's are set up using deferred SQL, which
in this case was trying to modify a table after it had dbeen removed.
