fix(lib): use correct URL for path checker in PassChallenge (#347)

Browse Source 
Otherwise, `r.URL.Path` was always `/.within.website/x/cmd/anubis/api/pass-challenge`
and this didn't match the path checker rules correctly,
which caused a failure when the difficulty of these rules was non-default.
