Bertrand Lorentz d9bef0d869 gtk: Fix creation of ComboBox and ComboBoxText subclasses with entry
When creating a subclass of ComboBox with an entry, the has-entry
property was not initialized, leading to a crash when trying to access
the entry.

For subclasses of ComboBoxText, two other properties were not
initialized, leading to Gtk-CRITICAL error messages.
