Model summarize displayed twice before training starts
🐛 Bug
Model summarize is called in two spots, which results in duplication in the logs:

It's called once in the training loop: https://github.com/PyTorchLightning/pytorch-lightning/blob/master/pytorch_lightning/trainer/training_loop.py#L160

And I'm unsure how it's called again

The first time is with the logger.info(...) since it's formatted. The second time it appears to be logged with print(...) since the table formatting doesn't handle newlines
To Reproduce
Run any training with weights_summary set on the trainer
Expected behavior
We only call summarize once
