reconnecting might better start the loop. proposed minimal fix.

hello friends,

studying this example, i came to the conclusion there might be an error.
in case of an unintended connection drop, a loop restart seems more fit to be issued, and not a stop thereof.

pika/examples/asynchronous_publisher_example.py

Line 105 in 444ea04

self._connection.ioloop.call_later(5, self._connection.ioloop.stop)

Sorry, I was unsubscribed from this repository and have missed new issues from the past year. I will investigate this before the next release, thank you!

This code will re-start the connection because self._stopping is still False.
