Since https://github.com/odoo/odoo/pull/110737, it is better to use `_read_group` instead of `read_group` in the backend. In fact, the public method is less efficient (it computes display_name of relational groupby, extra order, ...) and more verbose. This commit replaces these new uses of `read_group` with `_read_group`. closes odoo/odoo#136381 Related: odoo/enterprise#47826 Signed-off-by: Raphael Collet <rco@odoo.com>
