util/sasl/external.lua @ 9203:c65bfddd3cc5

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.
