  [ews] Optimization to reduce number of results database lookups

Reviewed by Ryan Haddad.

When there are lot of test failures, we consult results db for every failure. However, we can bypass
the retry logic only if ALL the test failures are pre-existing. If even one failure is not pre-existing,
we can't benefit from results database lookups. So, we can optimize the number of results database calls,
by skipping consulting results-db for further tests the moment we know that one of the test failure
is not pre-existing.
