Fix crash when opening the gallery

ConvertOf is an x:Bind function binding over ViewModel.SelectedItem, and
Bindings.Update runs from Load before an item has been selected, so the very
first evaluation dereferenced a null GalleryMedia.

ConvertCaption in the same file already guards its input the same way.

Reported by crash telemetry on 12.9.0.0.
