Thomas Tauber-Marshall 8b5cb576d2 IMPALA-8173: Fix KeyError in run-workload.py ...

A recent change (IMPALA-7694) causes run-workload.py to fail with a
KeyError due to trying to construct an ImpalaBeeswaxResult without a
query id.

This patch fixes that issue and two related issues:
- This problem was not caught by automated testing even though we run
  run-workload.py in run-all-tests.sh because of an issue where
  queries that fail to produce results are silently ignored.
- Fixes an issue where queries that fail to produce results would
  confusingly produce the error:
  'NoneType' object has no attribute 'time_taken'

Testing:
- Ran run-workload.py locally and demonstrated that it works now.
- Ran run-all-tests.sh locally and demonstrated that it fails now when
  the KeyError issue isn't fixed.
