only assign svgimage source if new value is not null

[DrCopyPaste]

(this might be the case for instance when changing/overriding the used resourcedictionary)

just a small change, I noticed this was the only error I was getting when I was trying to switch application wide styles, because I suppose it would leave the svgimage without a value when removing the currently used resource dictionary before applying a new one - hence ignore empty values in OnSourceChanged...

Probably could make sense to do this check for UriSource too, but I just tested it for Source ;) I got a working example here https://github.com/DrCopyPaste/RecNForget/tree/feature/embedForkSvgImage

And what's the case if you'd like to set it to null? (for example to remove the image?) How does the WPF Image COntrol work in this way? will it also ignore? I think we should do the same.

Yes of course you are right, standard Image control allows setting to null, I have updated the branch so this now also works for svgimage
