Init addons and their dependencies before tests

Speed up testing
Skip tests of modules outside repo

Travis should not be running unittests other than the ones in the repo
Odoo will test every module it initializes, this is why the `setting up the database` should also install the `tested_addons`, thereby installing the dependencies without having to run their tests each time.
