[FIX] hr: soft-prevent read of employees forbidden field

Before this commit, when having a simple employee (group employee) accessing the form view
of hr.employee, there was traceback because the field is_address_home_a_company was not in the view

This is because of commit 2d777d5
which restricted this field to the group_hr_user (Officer) in Python

When the view itself is not group-restricted
The JS loads everything from the view but puts invisible=1 on sections that have a group

The field, in our case, is forbidden before that and is not loaded, whereas the domain in which it is used is loaded

After this commit, the view loads correctly, while avoiding leaks as intended
