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.

# This test checks mutations concurrent execution with concurrent inserts.
# There was a bug in mutations finalization, when mutation finishes not after all
# MUTATE_PART tasks execution, but after GET of already mutated part from other replica.
# To test it we stop some replicas to delay fetch of required parts for mutation.
# Since our replication queue executing tasks concurrently it may happen, that we dowload already mutated
# part before source part.
