New/updated file extensions not in alphabetical order in the results list

Overview: When creating or updating an existing file extension, the newly-saved file extension does not automatically sort into alphabetical order in the list of file extensions. This is not a critical bug, but it is weird-looking behavior to the user (at least if the user is me!)

Steps to Reproduce:

1. Log into FOLIO-snapshot as diku_admin
2. Go to settings/data import/file extensions
3. Create a new file extension, or edit an existing one
4. Save your work and look at the list of file extensions

Expected Results: The new or updated file extension should be in alphabetical order by file extension (if you haven't re-sorted the list by any of the other column headers). Default sort order for the list should be ascending by file extension.

Actual Results: They sometimes show up at the bottom or in the middle of the list, not alphabetical - even when the arrow on the column header indicates they should be in alphabetical order
