[10.0][FIX] web_access_rule_buttons

This fixes a bug occurring when creating, with the same operation, a record plus one or more o2m, m2m or m2o records related to it. In this scenario, invoking check_access_rule() will crash reporting an error like DataError: Invalid input syntax for integer "one2many_v_id_42" trying to execute a query using a string instead of an integer.
