  [ews-build.webkit.org] Handle missing commit record

Reviewed by Ryan Haddad.

Not all commits EWS tests have been reported to results.webkit.org. This
may be because merge-queue is ahead of post-commit infrastructure, or because
we collapse build requests on build.webkit.org. We can easily detect this case,
though, an use tip-of-tree as our baseline instead.

* Tools/CISupport/ews-build/results_db.py:
(ResultsDatabase.is_test_expected_to):
(ResultsDatabase.has_commit): Return True if the commit record exists, false if it does not.
* Tools/CISupport/ews-build/steps.py:
(RunWebKitTests.filter_failures_using_results_db):
