Wayland: Fix duplicate monitor connection events

Browse Source 
GLFW would report a monitor as connected each time its wl_output
received an update, for example if its scale changed.

This would also cause the monitor to be added to the monitor array
again, causing glfwTerminate to segfault when it attempted to destroy
its already destroyed wl_output.
