Fix various bugs uncovered by the LIST system

* Work around Twisted's broken handling of spaces
* Work around Twisted's broken line decoding
* Don't run signedOn twice for relays
* Improved detection of whether the endpoint is connected to ZNC
* Delay a LIST until all configured relays are online
* Discard a LIST if there are no callbacks for it
* Get rid of some double-negative ternary blocks
