The history of the replenishment info may be empty while it should not
To reproduce the issue:
(Set your device on January)
1. Process a delivery for product P
2. (Inventory > Operations > Replenishment, create a new one for P)
3. Click on the information icon (I) of the P's line
Error: The sales history does contain anything
When calling `relativedelta`, `month` is considered as an absolute value
and will replace the corresponding value while `months` is a relative
value and will be added/subtracted to the corresponding value.
