Story: BI-2656

This fixes a bug discovered in QA while testing BI-2656.

Testing

Optionally run through this procedure on release/1.1.1 first to reproduce the bug.

1. Upload germplasm, ontology and this experiment with two observation units and one observation value plus timestamp.
2. Download the experiment, and edit the file.
   • Row 1: Delete the observation value and timestamp (make those cells blank).
   • Row 2: Add a new observation value and timestamp.
   • Save file.
3. Upload the edited file using the "Append" workflow.
   • Ensure the preview shows the correct statistics and does not indicate that data is being overwritten.
   • Ensure the upload completes successfully on confirm.
