Bug description

The app config value for cachbuster of theming is constantly rising. This prevents caching on frontend resources, and has side effects on Talk. Because this is used in calculating a hash, it appears that resources were changed and requires a reload. This happens infinitely.

This was introduced in #34432 specifically the added lines 227 and 230 in apps/theming/lib/ThemingDefaults.php. The behaviour becomes normal when the lines are commented out, alas this may have other side effects I am not aware of.

Steps to reproduce

  1. Run Nextcloud 25 RC3 (earlier versions not affected)
  2. Have Nextcloud Talk open

Expected behavior

Talk does not think the instances was updated every 30s.
