Fix application quit behavior in single-process mode

Single-process mode QML applications had the finish() callback invoked
twice, if a fade-out animation was running on a window.

While at it, fixed the 'kill' stop flag to be more in line with the
multi-process case and also updated the debug output on application
stop to the newer, more readable style used by the native runtime.
