urlapi: fix parsing ipv6 with zone index

The previous fix for parsing IPv6 URLs with a zone index was a paddle
short for URLs without an explicit port. Fix for this case and add a
unit test case.

This bug was highlighted by issue #3408, and while it's not the full
fix for the problem there it is an isolated bug that should be fixed.
