[MERGE] various: Make the test suite demo data independant

Purpose
=======

This is the first huge step to improve the test suite in several ways:

- Make them demo data independent, allowing to modify the demo data without having to adapt the tests depending on it. It also allows to have a beautiful + convenient demo dataset to make a demonstration, and to configure complex data in the tests to manage the corner cases.
- Improve the test performances by converting them into SavepointCase. Each test will be rollbacked to it's initial state, after the setUpClass call. That way the different data are not re-created at each test for nothing.
- Introduce several test classes in base/tests/common.py to launch a TransactionCase, HttpCase or SavepointCase test with an available demo user, portal user or a large set of partners.
- This is the first step to tend to a rolling release process, allowing to execute the tests (or a subset of the tests) on a migrated base, for example.
