fix: always call WandbLogger.experiment first in _call_setup_hook to ensure tensorboard logs can sync to wandb

[ringohoffman]

What does this PR do?

In lightning.pytorch.trainer.call._call_setup_hook, sort the logger list when calling experiment on all loggers for the first time so that WandbLogger.experiment is always called before TensorboardLogger.experiment.

This ensures that wandb.init() is called before any tensorboard SummaryWriter are created, thereby guaranteeing that tensorboard logs can be synchronized to Weights and Biases.

See:

• TensorBoard not syncing with wandb wandb/wandb#1782 (comment)

Also from the Weights and Biases tensorboard integrations page:

You must call either wandb.init or wandb.tensorboard.patch before calling tf.summary.create_file_writer or constructing a SummaryWriter via torch.utils.tensorboard.
