    Refresh peer address if DNS unavailable at peer creation
    
    If Asterisk starts and no DNS is available, outbound registrations will fail
    indefinitely. This patch copies the address from the sip_registry struct, which
    will be updated, to the peer->addr when necessary.
    
    If dnsmgr is enabled, the registration fails without the patch because even
    though the address on the registry is updated via dnsmgr, the address is just
    copied on the first try. Since we use ast_sockaddr_copy, dnsmgr can't update
    the address that is copied to the sip_pvt or peers.
    
    Closes issue ASTERISK-18000
