KonvergoWindow: fix some more resize issues

The webScaleChanged signal does not only affect webScale. Who would have
thought? It's needed for normal resize events too. So remove the signal
from notifyScale() (where it's evidently useless), and emit it on every
potential size change. Also, the return value of some properties which
use "NOTIFY webScaleChanged" depend on other stuff, like the desktop
mode, so move the signal emission to until after all these things have
changed.
