Make pagination work on photo album overview page

[githubertus]

and display profile picture album and profile cover only on page 1

Actually, I'm not quite happy with the hardcoded page limit in photos
Maybe it's better to get the value from the hook instead.

But the real problem is:
GetAlbums() is calling getObjectByOwner()
and getObjectByOwner() is setting page_limit to something empty
Now when getObjectByOwner() is calling searchObject()
the array_merge($default, $params); will overwrite the $defaults array page_limit (of 10) with the empty $params page_limit
leading to a crash finally.
see array_merge doc: "...If the input arrays have the same string keys, then the later value for that key will overwrite the previous one. ...."

So, as long as you don't want to make any changes to Ossn_Objects, the page_limit must be set BEFORE calling getObjectByOwner(), as in this case via GetAlbums()
