[FIX] hr: fix employee creation from user form

Issue

- Install Employees
- Create a new user
- Click on "Create employee"

Traceback

Cause

In 999ced42989f, we add the user_id key but we
already have in the action_create_employee method

The key is duplicated so this is why there is a
traceback

Solution

Remove the key in action_create_employee since
we have it in _sync_user
