Backed out changeset 27d800ddc3b0 (see below)

It's uncertain whether item not existing should be success and
nil, or fail with an error.

XEP-0060's "fetch most recent item" actually fetches a list of up
to N items. N here is a maximum, not a minimum. The feeling is that
no items is simply an empty list, not a failure of the operation.
