[FIX] project: add default description with quick create

Steps to reproduce:
-------------------
- to be in debug mode;
- add a description in an existing task;
- go to Set Defaults in the debug mode;
- add a default description;
- add project id as a condition;
- go to the kanban view of the project;
- create a task;

Issue:
------
Default description is not present.

Cause:
------
The description must be added as a parameter
to the onchange in order to be set to the default value.
The fields passed as parameters are the view's active fields.
Active fields are found during  parsing
of the `quick_create_task_form` view arch.
Unfortunately, the latter does not contain the `description` field.

Solution:
---------
Add `description` field to be detected as an active field
of the quick create view.
