Optimize CI test runtime

This PR makes 2 main changes to the tests:
1. User logins were a huge part of the total CPU time because of the constant hashing of the password. There were 3 logins every time for every `Setup()` call. We remove the `LoginSystemManager` from the Setup call as it wasn't used in a lot of tests, and call that as needed.
2. We add the new app migrations that got added after the last preload optimization was done.

This shaves off around 3 mins from the test runtime. They are down from ~18m to ~15m.

```release-note
NONE
