Azat Khuzhin d28963d695 tests: do not leave any queries after finish
This should fix issues like [1], where because one query from the
previous test was left the next fails, in this particular report the
problem was that 01281_group_by_limit_memory_tracking fails due to the
query from 01301_aggregate_state_exception_memory_leak was running in
background.
