Julian Winkler 36b6132324 fix reference counting for GtkWidgets created from java
GtkWidgets extend GInitiallyUnowned and are automatically freed when
removing from parent widget. We need to add an extra reference, to make
sure the object keeps alive as long as the java widget has a reference
to it
