Clarify warning message: Update the warning to explicitly state that the model configuration is being loaded, rather than a model from Stanford NLP.

[NohTow]

About the warning message: we not only load the configuration of the stanford-nlp model, but also the weights.
Actually, we more load the weights than the config, as I wanted to load more information from the model config by reading artificat.metada, such as the max doc/query length.
