The unittest signature of `assertRaises` allows a named parameter `msg`[1]. The message is displayed in case of assertion failure if `assertRaises` is used as a context manager (but not when giving it a callable). The Odoo implementation did not implement this behavior, despite it being expected by multiple odoo tests. Fix Odoo version to be in line with the method we're overriding / shadowing.
