re-enable DPO for tests in modal ci (#1374)

* re-enable DPO for tests in modal ci

* workaround for training args

* don't mixin AxolotlTrainingArguments

* fix mixin order so MRO doesn't result in

TypeError: non-default argument follows default argument error

* use smaller datasets for dpo tests
