[FIX] Remove obsolete instruct (JS) in openerp.py

Remove obsolete instruct (JS) in __openerp__.py
In the new version of Odoo the JS is appended using template and xpath
Check this file : view/res_users_view
It's a copy paste from another module,
check here : https://github.com/odoo/odoo/blob/master/addons/web_tests/views/web_tests.xml
I took inspiration from the web_tests module to inject javascript.
