Optimize discussion notes resolving and unresolving21109-discussion-resolve-runs-a-single-update-query-per-note-but-should-run-a-single-update-query-for-all-notes-instead

update the notes resolved status. Some changes had to be made to
the discussion spec to accout for the fact that notes are not
individually updated now
