 * @assertion String splitMapJoin(
 *  Pattern pattern, {
 *  String onMatch(
 *  Match match
 *  ),
 *  String onNonMatch(
 *  String nonMatch
 *  )
 *  })
 *  Splits the string, converts its parts, and combines them into a new string.
 *
 *  pattern is used to split the string into parts and separating matches.
 *
 *  Each match is converted to a string by calling onMatch. If onMatch is
 *  omitted, the matched string is used.
 *
 *  Each non-matched part is converted by a call to onNonMatch. If onNonMatch is
 *  omitted, the non-matching part is used.
 *
 *  Then all the converted parts are combined into the resulting string.
 * @description Checks that match argument of onNonMatch method is correct
