Hi,

I ran into a case where I am trying get_many with empty list, in that case, debug toolbar is throwing exception and the toolbar is not appearing. Here I came up with a fix. I think that if return_value is None it's neither a cache miss nor a cache hit right??? Please review and merge if the code is correct.

Hey @robhudson and @aaugustin,

can you both review the above PR ???
