Improve "Find Owners" action button appearance.

* When switching PolyGerrit pages, the "Find Owners" button
  could be hidden or lost. Previous change to un-hidden the
  button does not work now. So we always create a new button
  and remove the old button.

* Add a 'robot' icon and hint message for the action button.

* Change the pop up window message to be more generic.
  Some Gerrit servers are configured with this plugin
  but do not enforce the owner approval rule in pre-submit checks.
