cc::input: Do not unescape input URIs
cc::input: Do not unescape input URIs

Rationale:
- This was previously done because quvi-dump(1) escaped the entire URLs
  (incl. the "reserved chars")

- cclive uses Glib::uri_parse_scheme to determine the action it should
  take with the input URL which would fail with the completely escaped
  URIs

- Applications would typically leave the "reserved chars" unescaped,
  e.g. the web browsers
