Check that the trainControl object supplied by the user is valid and has defined re-sampling indexes.
This function checks the user-supplied trainControl object and makes sure it has all the required fields. If the resampling indexes are missing, it adds them to the model. If savePredictions=FALSE or "none", this function sets it to "final".
