[stable31] Fix empty photos/people tab

[Marraz]

The tap does show the faces recognized but clicking in any of them doesn't show anything.
Can't go into master since it have been refactor.

[Marraz]

Fix for #3105
This is already fix in master since this whole file was refactor so it shouldn't apply to v32

@Marraz can you compile and commit the files ?

[artonge]

@Marraz please remove the merge commit. If you want to update your branch, you can rebase it. :).

@artonge Done, let me know if there is something else missing

Thank you @Marraz :)
