LibWeb: Fix null dereference when assigning an ImageStyleValue via JS
When parsing a CSS value in the context of a CSSStyleDeclaration camelCase property setter, we don't necessarily have a Document to provide the CSS parser for context. So the parser can't go assuming that there's always a Document in the ParsingContext. And ImageStyleValue can't go assuming that there's always a Document either. This will require some more work to get things right, I'm just patching up the null dereference for now.
