Add check if IPv4, IPv6 are valid JID domain part
When creating a JID we were not checking if a
domain part is a valid IPv4, IPv6 addresses. We were
only checking if the domain is correct according to
internationalized domain name rules which was failing
for IPv6 addresses.
Test-Information:
Unit tests pass on Windows 10 and Ubuntu 18.04.1 LTS
