Fix confusing intersect/filter methods naming/behaviour.

Removed rcube_result_index::intersect() method.
Changed rcube_result_index::filter() to filter in the same way as
rcube_result_thread::filter(), which means it actually does array_intersect().
Added tests scripts for rcube_result_index class.
