Temporary fix for failing CI for master branch

TestHTTPExecuteDeployTransaction is failing on master
because it is trying to go get
http://github.com/hyperledger/fabric-test-resources/examples/chaincode/go/chaincode_example01
which implements new interfaces from the convergence branch.
This patch points the test at a different repo for now and demonstrates usage of
gopkg.in to attempt to overcome limitations of go versioning

Fixes FAB-305
