Caused by 'rss announce add' triggering headline announces, that would
delay the execution of the 'remove' commands.
Thanks to @mapreri and @Unit193 for help in reproducing the issue
and confirming the patch.
This is because the recommended method ('owner ircquote nickserv register mypassword bot@example.com')
does not work on charybdis, as Limnoria inserts a colon
before the trailing argument and Charybdis' m_alias module
does not parse commands using the IRC syntax, so it
considers the leading colon to be part of the email address.
The alternative would be to change the recommended command to:
'owner ircquote PRIVMSG nickserv :register mypassword bot@example.com'
but it is prone to typos, so I think we should avoid it.
feedparser should always catch the error, but someone reported it doesn't
catch this error on TLS cert issues:

So let's catch the error just in case, so it doesn't block all other
feeds.
It mistakenly used the bot's nick as target when the message is in private,
so 'more' after a private message always answered the user did not send
a command before (because said command was attributed to the bot)
The default behavior was to announce feeds on all channels with the same name,
which is rarely what was expected.
Instead, this limits it to the current network.
Until now, only `waitingJoins` was stored separately per network, while
`channels`, `sentGhost` and `identified` had one common value per plugin
instance. Instead of making everything a dictionary indexed by network
name like `waitingJoins`, let's bundle all the state together in a class
and store *its* instances in such a dictionary.
This fixes at least one race condition, for which a test case was added.
Even with `noJoinsUntilIdentified` set, the bot would let joins through
as long as *any* one network has already finished identifying.
I didn't observe any error with the current set of tests but adding
another one that used "services password" caused oen of these tests
to fail. Given that tests shouldn't leave traces in global state,
let's reset the configured passwords in finally blocks.
