Remove assert check for revert_submission submission

Change 304491 cleaned up sending the revert_submission action as
part of the change actions response however the API to revert the
submission still exists.

This cleanup caused assertUIActionInfo to throw an error since the
action was no longer a part of the response.

Change 306562 has been submitted to rollback Change 304491.

Hence, temporarily bypass the check for the action so that revert
submission can still be done and clean this up once the BE change has
been fully rolled out and stable since we don't want the working of
revert submission to depend on the status of the BE rollout.
