    soup-session: Force cleanup of REMOTE_DISCONNECTED conns for sync sessions
    
    get_connection() assumed that REMOTE_DISCONNECTED connections would get
    implicitly cleaned up elsewhere in the code, which is true for async
    sessions, but not sync ones. This could lead to connection exhaustion and
    hence hangs.
