Title: [FIX] Some modules are not marked for upgrade with -u all

In standard Odoo, '--update all' just means: '--update base + upward (installed) dependencies'.
This breaks the chain when only new (glue) modules are encountered. E.g. purchase in 8.0 depends
on stock_account and report, both of which are new. They may be installed, but purchase as an
upward dependency is not selected for upgrade. Therefore, explicitely select all installed
modules for upgrading in OpenUpgrade.
