What happened

Repro:
• Use image batch node
• Add 5 images
• Go to canvas to generate more
• Delete any of those 5 images
• Go to workflow > hard crash

You'll be in permanent lock until you fix the workflow. (Unless there is an easier workaround)

Workaround:
• Remove the images in the workflow in invokeai.db
• Restart the server
• Clear the db instance cached on your browser (need more than a hard reset)

What you expected to happen

Alert user of missing images and clear out the batch
