fix(migrations): Patch broken saved search migrations

[malwilley]

Fixes getsentry/self-hosted#3766

This is what happened with the bad migrations:

• 0917 was added, but it failed when running the post-deploy script
• 0920 was added and checked for the missing owner ID, but also failed
• 0921 was added and fixed another bug. This one succeeded

However, we never went back and removed the old failing migrations. Because they were post-deployment and never successfully run, I believe it's okay to make them noops.
