Summary Check CachedResourceLoader's document WeakPtr in more places

The CachedResourceLoader class holds a WeakPtr to a Document, which may be nullptr at different moments in loading. We inconsistently check for nullptr, which telemetry shows is triggering some crashes. This patch provides more rigorous checks for nullptr to avoid these crashes.
