Favorite view sorts by upload date, should sort by creation date

Steps to reproduce

Go to "Favorites"

Expected behaviour

Sorting "from old to new" should sort media data by creation date

Actual behaviour

Seems like data is sorted by upload date

Screenshots

If applicable, add a screenshot showing the issue.

Logs

If applicable, you can post the iOS app or server logs (removing any sensitive information).

Reasoning or why should it be changed/implemented?

The way it is implemented now, favorites are being sort by upload date, which doesn't really reflect reality, since the sequence is pretty arbitrarily, and so "things that happened afterwards" are being displayed "before" in some cases. Sorting by creation date would solve this (like it is implemented in media view, where you can choose between change, creation and upload date).

Start by reproducing the ordering in the Favorites view on the iOS app using media with different creation and upload dates. Trace the Favorites sorting entry point and verify that sorting from old to new uses creation date, then confirm the displayed order matches the media view behavior.
