Add missing skipKey() in array() and object() methods

This change facilitates parsing sequences like

  if (reader.isKey("name)) {
      reader.beginArray();
      ...
  }
  if (reader.isKey("name)) {
      reader.beginObject();
      ...
  }

without the need for an extra reader.key() before the beginArray()
or beginObject() respectively.
