[7.0]add attendance in timesheet sheet

[Laetitia Gangloff (Acsone)]

Hello,

it seems there is a problem with "Add item" button in the timesheet sheet on attendance.

To reproduce:
- use the head of lp:~openerp/openobject-addons/7.0
- create a new 7.0 db without demo data
- install "Timesheets" apps
- grant "technical features" and "attendances" to admin user
- create an user (Settings/Users/Users)
- create an employee (Human Resources/Human Resources/Employees) related to the new user
- create a new timesheet for this new employee (Human Resources/Time Tracking/Timesheets to Validate)
- in the tab Attendances click on "Add an item" (in attendance_ids tree)
- after filed the information, click on "Save" button

=> There is no row in the tree

It seems that the created attendance is associated to the connected user.

Thank for your help.

Laetitia
