IMPALA-1395: Remove slow test for IMPALA-1312 that breaks exhaustive runs

Removing the test case for IMPALA-1312 to unblock exhaustive runs. This query was
previously hitting a DCHECK failure in the BufferedTupleStream where the number of
pinned blocks wasn't being updated properly. With codegen enabled, this query took
~70sec. Without codegen, it took so long that the exhaustive runs would fail- I
found it took ~35min on my local machine.

IMPALA-1414 tracks investigating why this query is so slow.
