fix(files_trashbin): create folder if missing when expiring trash

[invario]

• Resolves: [Bug]: files_trashbin logged NotFoundException /USERNAME/files_trashbin Error while expiring trashbin for user USERNAME #61224

Summary

If the background job to expire trash was executed before a user had ever trashed a file, the files_trashbin folder would be missing and an exception was thrown. Change the method used from get to getOrCreateFolder instead.

Backport to 33 shouldn't be needed as the offending code isn't present yet (introduced in commit a8d69ff).

Also, thanks for the merge!

yes, in NC 33, the bug didn't occur. So, no backport needed.
