Commit https://github.com/odoo/odoo/commit/eb0ea8efbe932c140302e9f8da33a839bcd73146 removed the use of the 'rte' and 'rte_inline' without removing the tests themselves. They apparently cannot work anymore as using routes which do not exist anymore. This commit removes the test files. Part of https://github.com/odoo/odoo/pull/41789
