This PR changes the "value fields" of SnippetChooserBlock, DocumentChooserBlock, ImageChooserBlock and PageChooserBlock grapple types to be nullable.
This will allow those blocks to handle referencing deleted objects. Users will be able to implement gracious failing where those blocks are used instead of having to handle grapple errors.
