/// @assertion Uri resolveUri(Uri reference)
/// Resolve reference as an URI relative to this.
///
/// Returns the resolved URI.
///
/// The algorithm "Transform Reference" for resolving a reference is described in
/// RFC-3986 Section 5.
///
/// Updated to handle the case where the base URI is just a relative path - that
/// is: when it has no scheme or authority and the path does not start with a
/// slash. In that case, the paths are combined without removing leading "..",
/// and an empty path is not converted to "/".
/// @description Checks that this method works correctly if schema and authority
/// are not provided but path is provided
/// (see https://tools.ietf.org/html/rfc3986#section-5.2.2)
