Preselect "Ticket holder" same as "Ticket Buyer

[mariobehling]

Always preselect "Ticket holder is the same as ticket buyer." by default, but keep functionality as is. So, the ticket buyer can untick the box if they want.

In the past I think we discussed to disable this feature for first time ticket buyers, but use this option for all others. As this feature has been reverted for now I am re-opening it.
