If name=None create_receiver is supposed to create a unique link ID. The
problem is that python (unlike other bindings) generates a name from the
container-id, source and target. So making 2 links between the same
source/target fails
Instead python should be generating a unique id like "container-id<counter>",
similar to other bindings.

> Project: Qpid Proton
> Issue Type: Bug
> Components: python-binding
> Affects Versions: proton-c-0.24.0
> Reporter: Chuck Rolke
> Priority: Major
>
> From DISPATCH-1114
> Creating a sender and a receiver in the same container produces duplicate
> link names. Try python/examples/helloworld.py that executes:
> event.container.create_receiver(conn, self.address)
> event.container.create_sender(conn, self.address)
> generates the same link name for each attach:
> (M=a1b7d *1 ?3) chug@ratchet examples> PN_TRACE_FRM=1 ./helloworld.py
> ...
> [0x55a01066d9a0]:0 -> @attach(18)
