In case only one cache clear option is available
in the toolbar (no dropdown), clicking on the icon
previously led to a blank page, since the corresponding
JS event listener did not get called and the tce_db
route was called directly.

This is now fixed by using the correct class to notify
the event listener, which will call tce_db in an ajax request.
