scenario with previous code:
auto_connect enabled, there is only one server in regtest environment.
client started before server; client would not switch to server after it is started.
The synchronizer would sometimes not send 'wallet_updated' triggers
if it was fast enough to do all the work between two 0.1 sec ticks.
(is_up_to_date() would return True both before and after)
It was disabled in 680df7d6b6 due to #4421,
but that has since been fixed.
Also related is #4060; and now that that is closed, the bridge transport
is not proxied anyway.
