merge bitcoin#22817: Avoid race after connect_nodes

Due to stricter checks, we can no longer start masternodes in parallel,
as entities used to process `to_connection` checks are reused before the
previous check is completed, resulting in an exception. Since we're
now validating the establishment of a two-way connection, we have to do
it one at a time.
