[FIX] website_event,website_event_sale: correction pricelist in event register

A recent fix c41d1d2 was made to select the related pricelist
to show the correct price of an event product.

This fix creates another bug in case of Ecommerce app
not installed, because the method get_current_pricelist
is defined in website_sale module.

We need to move the fix from website_event to website_event_sale module.
