#102 Write originalUser() to ticket table for sales analisis

[NicaBerti]

If one has different sellers, but just one cashier, there is no information in the database, to analize, how much sold one seller.

There is already the printOriginalUser () for tickets, but it does not write it to the database. With the originalUser in the ticket table, one can create a report how much sales a seller realized, and what amount of money the seller moved.
