Fix migration specs using factories

Closes #62911

See merge request gitlab-org/gitlab-ce!29350

We need to stub default_git_depth and default_git_depth= because some
old migrations specs try to create a record using schema before that
column was introduced.

The `let!` calls were executed before the `before` hook which still
caused some factories to fail, so they're created in the `before` hook
now as well.

**Why?**
The styles applied to `.build-page .top-bar` were mostly
unecessary for the IDE terminal. The static positioning might
have also been causing a strange line to show up in the terminal.
