parse.HostPortorFile: return error when 0 found (#3742)

* parse.HostPortorFile: return error when 0 found

Return an error when we haven't found any nameservers. This is the
alternative considered in #3735. It's also slighly less code to be
changing.

Replaces: #3741
Closes: #3741 #3735

* Add extra test case here as well
