Connect to notifier.windowCreated from Extension fails

Hi @scottyp

Trying to use the windowCreated() and it doesn’t work with 4.4.0-alpha (git 71645c6)

Got error TypeError: connect() failed between windowCreated(Window*) and unislot() with following code:

@pyqtSlot()
def on_window_created():
    print('Test--on_window_created')

krita.Krita.instance().notifier().windowCreated.connect(on_window_created)

It works perfectly with 5.0.0-prealpha (git 8f2fe10)

My question is: bug fix will only be available for 5.0.0 and not 4.4.0?
