    window-tracker: Fix pid based window/app association
    
    The lookup table used by get_app_from_window_pid contained only pids of
    apps launched by gnome-shell itself, but not pids of apps running before
    gnome-shell was (re-)started. Also the pids in that table might not even
    be the pid of the process that is actually showing the window if wrapper
    scripts are used.
    
    Instead use shell_window_tracker_get_app_from_pid which uses the pids
    from the windows themselves.
    
    This removes the only use of launched_pid_to_app which will be removed
    in the following commit.
    
    This fixes: https://bugzilla.gnome.org/show_bug.cgi?id=736527
