IMPALA-1451: Empty Row in HBase triggers NPE in Planner

If for some reason an empty row is returned during a scan of an HBase
table, we have to make sure it is ignored.  Otherwise, it will trigger a
NPE when accessing either the row key or the value.

to an ignored test when both PLAN and DISTRIBUTEDPLAN sections were empty.
