fix: deselect deleted images on props update

[philipjackson]

Description

Fixes the crash that happens when deleting an image. Was happening because this.state.selectedImagesUid wasn't updating when images were deleted, so it was still trying to find a selected image that no longer existed, getting undefined from find, and passing that into MetadataDrawer. Rather than deselect the image when the callback is fired, which still allows the crash to happen if for some reason the user re-selects the image before it disappears, I've gone with updating selectedImagesUid in componentDidUpdate when the props change.
