If you call Bucket.find with a :prefix that doesn't exist on S3, instead of returning the expected empty array, it will
return all objects in the bucket!

This is because it will do a 'reload!' any time the object cache is empty -- but when it does the reload, it no longer
has the options hash, so it reloads all items for the bucket.

I've added a new flag to track whether the objects have been loaded, which fixes the problem.  I'm not quite sure how
to write tests for this, though...

Of course, I didn't get the right version of the patch
uploaded before.  Here's a corrected version.
