Removing attendees from a reservation doesn't update the invoice

[salmar]

When an attendee is removed from a reservation (and refund is done), the invoice should be updated accordingly.

Hi @salmar, thanks for opening this issue.

As per #407, starting from 1.14 alf.io will always update the invoice/receipt in case of PENDING reservation modifications.

We (@syjer and I) are not entirely sure that updating a confirmed (and paid) reservation should always trigger an update on the invoice, since in some countries this is forbidden.
For example in Italy the invoice must remain the same, and you must issue a "Credit Note" for the refunded amount.

So it's not "safe" to update the invoice as default behavior.

We were thinking of adding an extra checkbox "Update Invoice" to the "Remove Ticket" view:

and then to add a row in the invoice, stating that a refund has been issued, something like

Refund -100.00 CHF

wdyt?

implementation can be considered done.
@mg-1999 could you please provide a translation for the following text?

This invoice has been updated after the cancellation of one or more tickets and the refund of {0}.

Thank you very much!

closing this as it is fixed and we're going to release 1.14.
Will add Dutch translation as soon as possible.

Translated text:
Dit factuur is geupdate na de annulering van een of meer tickets en de terugbetaling van {0}.
