If auto_connect is enabled, allow jumping between forks too.
(Previously auto_connect was only switching servers on a given fork,
not across forks)
If there is a preferred fork set, jump to that (and stay);
if there isn't, always jump to the longest fork.

this is a performance optimisation.
measurements using a large wallet with 11k txns:
syncing XPUB for the first time takes 10 seconds. leaving window open, and
syncing same XPUB again in new window takes 30 seconds. in third window,
it takes ~50 seconds. then ~70s. presumably scaling linearly.
this is due to the history_list.update_item call being CPU-heavy.
now all of them take 10 seconds.
