[FIX] website_event: do not tell yet-to-come events are closed

Currently if an event has tickets, some of them with start date and some of
them without, it is considered has beginning at the minimal start date.
However if a ticket has no start date and is not expired, it means it is
available for sale.

An event start date is therefore the first date of its not expired tickets if
they all have a date, otherwise it is set to False (aka, already started).

We also fix display in main event page: events not yet open are not considered
as Sold out or Closed anymore, just not yet open.
