[KPhotoAlbum] People and Locations categories not loaded anymore

[Johannes Zarl]

Hi Tobias,

Sorry, I didn't see that you were working on a solution, as well. In the 
meantime, I have pushed my own solution, which can be seen in commit 015ccf0.

Could you please all check whether the fix in git master works for your 
database correctly?

@Christoph: Sorry again for breaking your database! I don't know how this 
could slip past me (especially since the bug affected my database as well!).

  Johannes
