IMPALA-7516: Fix query location accounting

As a side-effect of IMPALA-5216, queries that were scheduled to be
executed but eventually got rejected or canceled before starting
execution (initializing the coordinator object) got added to the
'query_locations' map but never got removed. As a result, the queries
debug page would sometimes show queries running under the
"Query Locations" section even if there weren't. This patch fixes that
behavior.

Testing:
Added a custom cluster test.
