Rusty Russell 2e6ad3ffc8 trace: handle key being freed while suspended. ...

This happens with autoclean, which does a datastore request then frees
the parent command without waiting for a response (see clean_finished).

This leaks a trace, and causes a crash if the pointer is later reused.

My solution is to create a trace variant which declares the trace key
to be a tal ptr and then we can clean up in the destructor if this happens.
This fixes the issue for me.
