This commit modifies the mixing client to consider fully formed sessions (where all peers have sent a KE with matching sessions), even if other sessions have already been attempted after. Previously, only the most recently attempted session would ever be used, and clients would only ratchet-down the peers they would mix with. With this change, initial session disagreement can be recovered from more gracefully, as some peers will form an alternate session matching the session that other peers originally tried. This commit also introduces a fix for a race that could result in root-solving wallets not publishing their solutions in a timely manner, which would result in non-solving wallets eventually being blamed for DC timeout.
This improves mix reliability in case a wallet is shut down while in the middle of a mix run. Requires additional wallet changes to properly order the shutdown of mixclient and the RPC/SPV syncers.
