Steps :
Create a recurrent task.
Delete it.
Run the cron "Create Recurring Tasks".
Issue :
IndexError: tuple index out of range.
Cause :
The cron calls a method which takes the last task of the recurrence
as a model. As there is no such task, an python error is thrown.
Fix :
Do not display the "Continue Recurrence" button when deleting the last
task of it.
