First eval loss logged as 0 with transformers==4.25.1

[stefanik12]

We found that in the version of transformers>=4.25.1, the first entry of objectives' evaluation loss gets a value of 0 (zero). This can cause preliminary early stopping in training configuration with StoppingStrategy.FIRST_OBJECTIVE_CONVERGED where no Evaluator(decides_convergence=True) is given among the Objective(val_evaluators).

Subsequently, the evaluation loss, logged with any training objective will look like on the picture below.

This behaviour is likely caused by a change in the implementation of transformers' Trainer after version 4.19.1 (where this issue does not occur) and before 4.25.1 where it has been registered.

After the issue is fixed, do not forget to open the required version of transformers in the adapter's setup.cfg; We temporarily fix it to version 4.19.1.
