Subject: [PATCH] [client] app: free the frame event after display server
 teardown

Display server and overlay teardown can still call app_invalidateWindow,
which signals the frame event; the Wayland presentation module does so
when it unregisters its graph. Freeing the event beforehand asserted in
lgSignalEvent while closing the client.
