[FIX] hr: Load the public views on load_views if no access to employees

Purpose
=======

On a many2many targeting the hr.employee model, if the user has no
access rights to the hr.employee model, clicking on a record of the
many2many will lead to a traceback.

Specification
=============

It's because load_views, called by the web client, will try to load
the form view on the hr.employee model. Overriding the method to
load the public employee form view instead if the user has no read
access is sufficient to solve the issue.

We could have overriden the methods fields_view_get and fields_get,
but it doesn't seem necessary yet.
