bugfix/free time slot on bill cancelation

[chris-dare]

Describe the bug Not able to reuse a time slot for a canceled encounter

Impact Money will be lost because patients can't consult with doctors when doctors are available

To Reproduce Steps to reproduce the behavior:

1. Switch to reception workspace
2. Start a visit for a patient
3. Switch to billing workspace
4. Attempt to cancel the patient's consultation bill
5. You'll notice that even though the bill has been canceled, the slot is still marked as busy when tried to book another patient for that time

Expected behavior Once we can cancel a bill for a consultation and the time is not yet due, the slot should be freed so that another patient can take it

@TuyizereBapt, I will update this so it's clearer where you can find this in the code

Hi @TuyizereBapt,

In finance.models.ChargeItemCancelation.cancel(*args):

• If the charge item has an encounter, set the slot that belongs to that encounter to SlotStatusType.FREE
