Unblock connection receive when context is done #781

When context is canceled we don't read anymore from t.incoming channel
because the select clause exists on ctx.Done. This change adds the
same behavior to the point where t.incoming channel is written.
Without this the call to conn.Receive could block forever given a
race condition between a context cancellation and a new incoming
message.

Furthermore, is always a good practice to listen to context.Done on
blocking points where a context variable is available.
