Website: the context install_filename='dummy' is used to prevent arch_updated from becoming True while updating translations of ir_ui_view.arch_db (if arch_update becomes True, test_inherit_specific fails) Fuzzy search for jsonb translated fields has been adapted in the case of website. It may require some refactoring later.
