Summary:
There was a bug in BlobCache where, if you had an interest handle to a
blob, but that blob was evicted anyway and then something else caused
it to be reloaded, dropping your interest handle would cause the blob
to be incorrectly evicted since the reference counts were no longer
compatible. Add a version to cache items and only decrement the
reference count on an item if the interest handle and item agree.
