After `init` command with UPnP fail, remember not to use UPnP
It seems that, even if an error occur with UPnP during init
command process, ucoin do not remember this problem and thereafter throw a:
ucoind - No UPnP gateway found: your node won't be reachable from the Internet. Use --noupnp option to avoid this message.
On ucoind start
command.
