[TestRun] Fix filter check on TestRun page

when a TestRun is filtered via query param (?status_id=) if you change
statuses then `stop_date` field will also change once all of the
filtered TestExecution rows become non-neutral.

This is a bug because the page isn't checking all TEs outside of the currently
filtered selection!
