Remove most values uselessly specified because giving the same value as
the default one (see _DEFAULT_MANIFEST in odoo/modules/module.py)
auto_install is Falsy by default
author is Odoo SA by default
summary & description are empty strings by default
application is False by default
test, demo, depends and data are empty lists by default
This will reduce noise/inconsistencies between manifests specifications,
simplify analysis of manifests content.
