Protocol receipts should not be signed in Austria

[TSchmiedlechner]

Problem

When using the ftReceiptcase 0x415400000000000D ("protocol"), it is signed if it includes ftChargeItems and the ftPayItems are empty. This means that these receipts are also included in the DEP7 export, but they shouldn't. This is incorrect according to the RKSV regulations and has been criticized by auditors in two cases now.

Solution

Protocol receipts without pay items shouldn't be signed either (and neither should be those with pay items, but that's already the case).

Warning

We will only change this behavior in 1.3.

Tasks

• Do not sign protocol receipts without pay items in 1.3
• Test in 1.3 (sample request below)
• Add unit/integration tests to reproduce the behavior
• Inform @mijomilicevic, so that he can reach out to the affected customers
