'Save Checkpoint' node automatically prunes all training weights

### Expected Behavior

When using the node by default, or when using `--force-fp32`, it should keep the training weights intact or at least provide you the option.

### Actual Behavior

It automatically removes all training weights as well as any other data it deems as junk. This brings an SD 1.5 model down to 3.5gb from 7.5gb when in fp32 precision.

### Steps to Reproduce

Load Checkpoint -> Save Checkpoint
