order root albums by path on settings page (#983)

Once you have more than a few paths assigned to a user, it becomes
quite hard to oversee the list.

Personally, I would add my albums to Photoview one by one, so I can
manage the processing better. For example, I can review and fix the face
recognition for one new album at a time, and I don't need to deal with
too much data.
Since I started to add the albums in a random order, it's relatively
hard to find which album is added and which is not.

An easy fix is to order the photo paths by their name.

- Extended the query of the rootAlbums to order them by path
