**Be totally deterministic about which views to use**
Having a primary view that is not explicitly declared to be uses and w/o priority
makes Odoo to choose between one of them randomly (well, not exactly, but kind of),
so we put here which views to use.
I have also put tree view as primary and put a large priority for not being
selected on other actions that don't have this explicit views.
A friendly name in views is also assigned.
**Improvements in tests**
* Use SavepointCase for making the setup only once for all tests
* Make them inheritable, creating a base class with only the setup,
so that it can be inherited without the need of executing all tests
contained here each time you inherit it, and adding other class
in the same module that inherits from the base class that actually
performs the tests.
* Removed duplicated test method
