window: Emit an error and return when trying to activate an unmanaged

Browse Source 
If something (i.e. gnome-shell or an extension) tries to activate an unmanaged
window, we should warn about this and avoid to perform further actions as this
could lead to a crash of mutter, since the window has not valid flags (like
workspace) set anymore at this stage.
