Using dev mode makes Fablo REST unusable

[joaormatos]

Trying to query or invoke using Fablo REST will result in a 400 Bad Request with a messages like:
message: 'Query failed. Errors: ["Error: Peer peer0.org1.example.com:7041 is not running chaincode myChaincode"]' for query, or
message: 'DiscoveryService: myChaincode error: failed constructing descriptor for chaincodes:<name:"myChaincode" > ' for invoke

I believe that this is due to dev mode peers not exposing connected chaincodes through the discovery service.

If no fix or workaround is possible, I believe a warning or error about this should be thrown when generating or running a configuration that uses both features.
