Subject: [PATCH 1/2] fix(setup): prevent unnecessary mime migrations on new
 installs

Avoids running the repairs for prior versions (that are otherwise a no-op) and also avoids the misleading/confusing setup check warning on new installations about "One oe more mimetype migrations are available [...]".

Subject: [PATCH 2/2] fix(Repair): make sure <v29 mime type repairs aren't
 skipped

- fix: Makes it impossible to accidentally skip pre-v29 mime repair steps even if one has skipped them up past v29. With the old behavior, when triggering mime type repair steps in an environment that's been upgraded from pre-v29 w/o running some steps, it was possible to never be able to run the earlier skipped steps. This change makes things consistent and clean.
- cleanup: Drops no longer needed 29.0.0.10 version check
