Find In Files Pagination Fixes

These 2 strings where using for the find in files pagination before the UI update, and I forgot to remove them. It is still to merge, since no other language has translated them, not even fr and ja. And is only a removal.

Update: I just found a nasty bug. The current start wasn't restored to 0 on a new search, so sometimes you could see no results at all.

@JeffryBooher Can you take a look please. We should merge this soon.
