Ignore previously deleted migrations
What does this MR do?
Rather than asking each contributor to sort out un-tracked files, we ignore the db/schema_migrations for previously deleted migrations
See #218590 (comment 387875844) (Thanks to @smcgivern for the idea!)
Testing
I have tested by touch
ing the files added into the .gitignore. The new files are ignored by git
grep schema_migrations .gitignore | xargs -n1 touch
