[url] IPv4 parser and the empty string as input (#96)

https://url.spec.whatwg.org/#concept-ipv4-parser

It is unclear what happen if the empty string is passed to the IPv4 parser as input.
The step 3 makes the "parts" list empty, and the algorithm gets stuck at the step 11.
(Probably, the algorithm should return the same input. )
