BUG/MEDIUM: checks: Refresh the conn-stream and the connection after a connect

When a connect rule is evaluated, the conn-stream and the connection must be
refreshed in tcpcheck_main(). Otherwise, in case of synchronous connect, these
variables point on outdated values (NULL for the first connect or released
otherwise).

No backport needed.
