* commons & setup refactoring:
* convert setUp to setUpClass
* move setups where needed (stock/mrp commons or specific test
classes)
* create test data in batch (faster, less sql queries & batched
operations)
* move most tests post-install to allow runbot splits
* by default, run tests without mail logic
* by default, run tests in a consistent environment (fixed currency
imposed in the BaseCommon)
* refactor existing tests to use new commons data (while trying to keep
diff reduced)
* add dedicated test file to test the common data
* use mute_logger to reduce useless test logs (less spam to scroll in
logs, less data on runbot builds, ...)
