glimagesink: need to clean window_id when state change form READY to NULL

Browse source 
When application change pipeline state NULL->READY and then READY->NULL,
glimagesink will not clear glsink->window_id. After that, when application
change state NULL->READY, the new_window_id is equal to window_id, glimagesink
will not set window handle. It will use the internal window but not the window
create by application.
