AK: Clear buffer after leaving CannotBeABaseUrlPath in URLParser

Browse source 
By not clearing the buffer, we were leaking the path part of a URL into
the query for URLs without an authority component (no '//host').

This could be seen most noticeably in mailto: URLs with header fields
set, as the query part of `mailto:user@example.com?subject=test` was
parsed to `user@example.comsubject=test`.

data: URLs didn't have this problem, because we have a special case for
parsing them.
