Made replication URL http
Made replication URL http

Cloudant https now uses SHA-2, the Erlang level for travis CouchDB
service is R14, but SHA-2 is not supported until Erlang 17.
Workaround by using http instead of https for replication, we are only
reading from the example animaldb to the travis couch instance anyway.
