[FIX] event_sale: ticket price is not correctly updated

When using the product configurator for event tickets the
price was not updated when picking a ticket with a different
price.
This of course is to the desired behavior.

This commit makes sure the unit price is correctly
recomputed when the ticket is modified on the SO
line.
