Currently, when making an import on the project. task and trying to enable the
'recurring_task' to True, the field is updated but a recurrence record is not
created.
Steps:
1. Create an import file of a new task record
2. Add 'recurring_task' field set to true
Technical Description:
The default value is not set when the file is imported. Such as repeat_interval,
repeat_unit etc. So we have called the default_get method.
