Cannot register payment of external event registration
I cannot register a payment of someone that is manually registered for an event, but is not a member of Thalia.
Current behaviour / Reproducing the bug
- Open an event
- Manually add an registration - not a member but fill in a empty name
- In the overview, change the payment from 'not paid' to 'pin' or 'cash'
- Reload the page, the payment is not registered
Should be clear I guess
