Fix clearing of picture (e.g. area and person config)

[spacegaier]

Breaking change

Proposed change

The change event of ha-file-upload was not reacted to in the ha-picture-upload so clearing was not possible.

Since this release brings the new area card with the picture being shown, I think this should go into the 2021.12 release still.
