fix: multiconnection loop not breaking after successfull connect

[Chr1s70ph]

BlockingConnection._init iterates over every URL in urls without stopping after a successful connect.

If the last node from the urls list was down, both inital connect and auto-reconnect failed even when other nodes were healthy.

@Chr1s70ph, since you are there. Can you please add a test for that?
