goconvey -host=0.0.0.0 uses tcp6 in stead of tcp

[IzakMarais]

I am trying to run the goconvey server binding to host 0.0.0.0. However, while the default 127.0.0.1 (or other IPS, eg. in the 172 range) binds correctly using tcp, 0.0.0.0 binds using tcp6:

Correct

A server listening on [::] can be reached on any local IP address, whether IPv4 or IPv6.
