Rare server connection issues (Tor bug?) #173

Long running clients very occasionally stop being able to connect to a Cwtch server without a Tor reset.

My suspicion is that occasionally the underlying Tor circuit breaks down in a weird way - basically Tor thinks the onion is unreachable even though it isn't - resetting Tor through the Tor settings screen in these cases does fix the connection issue.

The tell tale sign of this error is if there are 2 profiles on the same cwtch client they will both be unable to connect to the same server (even though they are instantiating different overlay connections). It's something I've been keeping an eye out for but it's rare enough that I've only seen it happen once.

I'm wondering if this is different than a long running client dropping the connection to a group chat? I ask because I often leave my laptop running all day (or longer) with Cwtch running and sometimes when I check Cwtch the connection to the Release Candidate Testers group chat has dropped and can only be reconnected by resetting the tor circuit. I'm on the Mac version 1.2.1 and I only have one profile.

I guess I should point out that the connection to fuzzbot, Dan and Sarah have not dropped in this scenario.
