SCRAM authentication fails

[felipeZ]

After running the docker command:

docker-compose  up -d crossbar lie_structures common_resources

All the microservices start and crossbar reports that all services all healthy.
Then when I try to run the microservices test, for example the common_resources test I get the following error:

2018-08-07T12:06:35+0200 Crossbar host is: localhost
