Title: Sorting on a non-existant range shouldn't die

Hey --

I think this fixes a bug that I ran across in my local switchover. Not sure if it is 100% compliant, but thought I'd send it your way.

If you do a zset request on a set which does not exist, I believe it should just return []. Without this fix it throws an exception.
