Add httptools failing test for long url

[euri10]

Does nothing for now, just shows the issue
May fix #924

@euri10 Can you rebase and see if we still have this issue, please? This should have been solved by httptools==0.2.0.

[euri10]

it's still failing in parsed_url = httptools.parse_url(url) which returns None everywhere for that length

[euri10]

kind of normal given the parser accepts url up to https://github.com/nodejs/http-parser/blob/ec8b5ee63f0e51191ea43bb0c6eac7bfbff3141d/http_parser.c#L31 so not sure we should handle that or ask it upstream this is the old parser...

re-edit in fact httptools still does the url parsing with http_parser so using httptools 0.2.0 wont improve things for us, since it doesnt change anything on that front
