Revert "Fixes for test_create_frame_rand1.py"

This reverts commit 7e17d2201303fd347b214aad22a09c16b4b61071.
Add more range checks to createFrame.
Assert that we have >=1 response factors, otherwise would make a String[0] which will lead to AIOOBE.
Remove invalid value for response_factors (cannot be 0 - see the comment!).
Inrease timeout needed for Summary2 when all columns are 100% NA.
