Summary:
change eina_tiler_intersection to return a NULL if intersection
of two tilers doesn't exist. and add test case to check it.
This doesn't break ABI/API as this call could already return a NULL value and it
should have been handled by the caller anyway. This just make an expected behavior
more correct.
Test Plan: run eina_suite after building eina test suite
