client: Do not warn about attached proxies on default queue destruction.

If the default queue is being destroyed, the client is disconnecting from the wl_display, so there is no possibility of subsequent events being queued to the destroyed default queue, which is what this warning is about.

Note that interacting with (e.g., destroying) a wl_proxy after its wl_display is destroyed is a certain memory error, and this warning will indirectly warn about this issue. However, this memory error should be detected and warned about through a more deliberate mechanism.
