When saving appointment in backend, capacity is set to 1.

[Valentina R]

To reproduce:

Book one appointment (product with capacity 5) with capacity 5. Then go to edit appointment and click save. And now the appointment has been saved with capacity 1. So now people can book it 4 more times - but it should not be available anymore.
