[xcb] Ensure the compositingChanged signal is emitted if NETEventFilter is
recreated
The Xcb implementation of KWindowSystem has two operations modes and when
switching between the two it recreates the NETEventFilter.
This could result in the compositingChanged signal never to be emitted if:
1) NETEventFilter gets created before compositor is started
2) NETEventFilter gets recreated after compositor is started but before
the old filter had a chance to process the XFixes event
This was the cause for e.g. plasmashell not properly detecting that a
Compositor is running on X11.
This change ensures that the signal is emitted if the compositing state
differs after the recreation. Also a test case is added which simulates
the condition.
