networkException 4230dbbb21 AK+Everywhere: Replace "protocol" with "scheme" url helpers 
URL had properly named replacements for protocol(), set_protocol() and
create_with_file_protocol() already. This patch removes these function
and updates all call sites to use the functions named according to the
specification.

See https://url.spec.whatwg.org/#concept-url-scheme
