[tor-commits] [snowflake/master] Added check for active pair in onopen

    Added check for active pair in onopen
    
    Because the timeout makes the pair inactive, we should check for this
    state in onopen before connecting to the client. Updated tests to set
    the proxy pair to active before testing onopen. Also removed a
    redundant statement.
