Current implementation of RabbitMQ driver in in Connection.reset() change
the channel to use and create a new channel for it. This happens after the
each message send.
There no big need to create a new channel each time, so we can cancel all
consumer queues, instead of creating a channel in reset().
Test test_connection_reset_always_succeed() removed, because we are not
create channel on reset() anymore.
