GtkFontButton: Make sure the dialog isn't destroyed on delete-event

The remaining code assumes that the dialog doesn't get destroyed, but
it actually does on delete-event.

In particular, the filter function and the preview text are lost as
soon as the dialog is created and thus when we create a new dialog we
don't have those properties to set on it anymore.
