client: fix crash when creating proxies with no queue

Browse source 
Before, it worked if the client did set a queue on the proxy before any event was received.
Now we have the "warning: queue xxx destroyed while proxies still attached", then a crash if one of
the proxies is used to create a proxy.

Fixes: 674145dc3f ("client: Track the proxies attached to a queue")
Fixes: 0ba650202e ("client: Warn when a queue is destroyed with attached proxies")
