add curated set of HuggingFace diffusers models for 2.3.1 release

- Final list can be found in invokeai/configs/INITIAL_MODELS.yaml

- After installing all the models, I discovered a bug in the file
  selection form that caused a crash when no remaining uninstalled
  models remained. So had to fix this.
