Bug: Rescheduling of chore with no stock of consumable fails with an error (silently)

Hi,

When a chore has a product, which has been completely used up (zero stock), to consume on its completion, the chore fails to reschedule to the next completion date:

• Via Web interface - the fail is silent: chore execution date is saved (even multiple times, if pressed more than once), but the following execution time will not be scheduled.
• Via Android app - the fail is an error (attached screenshot): execution date is saved, but no reschedule.

I think the expected behavior would be:

1. Automatic reschedule but with a warning that the stock is at zero and the next chore execution will not be possible unless restocked.
2. Block an execution of a chore if the required consumable is not available - with a proper message for the user.

Best, Jacek
