Steps:
Enable recurrence feature.
Go to Project > Office Design > Customer Review.
Enable recurrence on this task > Change month to year.
Issue:
Crash.
Cause:
`_get_next_recurring_dates` is called without a `repeat_month` arg.
Is is supposed to be a string which is going to be found in MONTHS keys.
Except it is False and so it is not in the list.
Fix:
If we don't receive it, deduce it from `date_start` arg.
