Clarification on lifecycle of refundOffers

[ralfbayer-db]

We need clarification on what happens when another refundOffer is requested while a previously requested refundOffer exists in the booking. Can we specify the behaviour?

Should also go to the documentation:

• after the validUntil has passed, the refundOffer is gone and can be re-created
• before that time has passed, no other refundOfferRequests can be sent, they would fail.
  -- either need to delete or confirm the previous refundOffer before creating a new one (or wait for it to be expire)

BookingParts also have afterSaleConditions where you have afterSaleFee for Refund or Exchange, and you do not need to get a refund offer. Would these amount match in Condition and RefundOffer?

Sqills: Can't have multiple refund offers in the same time.

Proposed as recommendation in the standard. TODO: Update documentation.
