Steps to reproduce:
	- get into an employee appraisal;
	- click on the smart button "No meeting" from calendar view;
	- edit it directly the meeting and save.

Issue:
	We will not find any new meeting on the smart button if we go back to the employee appraisal page.

Cause:
	When saving the appraisal from the edit view, an event will be created. Unfortunately, the `res_id` field (which allows it to be linked to a record in the `hr_appraisal` table) is not correct. The smart button that is attached to the `hr_appraisal` model will not detect that there is an event.

Solution:
	Don't accept a `res_id` which is zero. If so, take the default `res_id` and update it in the dictionnary that will be used to create the event.
