docs: Sorts the entries by a field, if the timestamp is equal, there is a fallback to the initial order.
  This can be possible if async requests are completed at exactly the same time or if the requests are
  added manually with the same timestamps (which are created if they are not provided). If this is the case
  the initial order is important.
  
  @param {object} aEntries The Array with har file entries to sort.
  @param {string} sFieldToSort Name of the field which is sorted.
