Handle empty list of id/revs in fabric:get_missing_revs
fabric_doc_missing_revs:go doesn't handle the case when AllIdsRevs is an
empty list (resulting in a timeout). Given this will always result
in an empty response, handle this explicitly and avoid the delegation /
aggregation from shards.
An alternative solution would be to fix fabric_doc_missing_revs:go to
prevent the time out rather than returning immediately. Comments on that
approach vs the proposed solution and guidance around where to add appropriate
tests for the original problem (POST to /_revs_diff with no revisions times out
in clustered CouchDB 2.0) would be much appreciated.
