fix embedded plugin UI keyboard handling

Browse source 
When the GUI is opened the first time all is fine, focus is on the
embedded widget. However once a user presses one of the preset buttons
(Add, Save,...) there is no possibility to return focus to the
embedded widget. Ardour always 'sees' it as focus=GtkButton and passes
the event to the editor.
