avatars are disordered in the availability section

[ruKurz]

Current behavior
When changing the code of a diary and switching back to the presentation view the avatars are mixed up (those whose status we know and those whose status we do not know). After switching into the edit view and back to the presentation view again, suddenly the avatars are ordered correctly.

Expected behavior
The avatar order should always be ordered. Those whose status is known should be placed first.

Steps to reproduce

1. Edit a diary
2. Enter some entires with an unknown status
3. Enter some entries with a known status
4. Switch to presentation view
5. => disordered presentation
6. Switch to edit view
7. Switch to presentation view
8. => ordered presentation
