An unknown error (including an unauthorized error) would fall through
with no calls to time.Sleep, resulting in hammering the server as
quickly as possible.
Add a 10-second sleep in the default error case. The heartbeat is
left with no explicit sleep, but all other codepaths now contain one.
Breaking change for zulip channel configuration.
For zulip the channel configuration will now need to specify also
the topic with /topic:yourtopic.
Example:
[[gateway.inout]]
account="zulip.streamchat"
channel="general/topic:mytopic"
This fixes the incorrect PR #701 which didn't work with multiple
gateways.
