muxrpc error when consuming alias

In Manyverse:

04-20 18:12:52.520 23046 23283 E ReactNativeJS: { message: 'failed to init connect call 
with target: error sending request: pkt-codec: header write failed: write tcp 
IPADDRESS_IN_FINLAND:8008->IPADDRESS_IN_HAMBURG:33578: write: broken pipe',
04-20 18:12:52.520 23046 23283 E ReactNativeJS:   name: 'Error',
04-20 18:12:52.520 23046 23283 E ReactNativeJS:   stack: '' }

Note that I redacted the IP addresses, but I'm quite sure it was my phone's IP address and @cryptix's IP address.

Oooh, one suspicion I have is that cryptix's SSB peer was offline. I noticed that the hermies.club dashboard mentioned that @QlCT (my desktop SSB peer) was online, although I had closed it more than 5min ago, so it was definitely offline. So that would explain the TCP failure, but what this means is that we need to fix go-ssb-room to not list offline SSB peers on the dashboard (nor in tunnel.endpoints) and that tunnel.connect to an offline peer should return an error such as https://github.com/ssbc/ssb-tunnel/blob/a8d209d13a662e6205017065600e736f473d5621/index.js#L182

This turned out to be a bug in ssb-room-client, safe to close.
