Failing tests when building janusgraph-examples standalone

[vtslab]

It was reported on the user list that janusgraph-examples as included in the binary distribution does not build in standalone fashion.

• Version: 0.6.0
• Link to discussed bug: https://lists.lfaidata.foundation/g/janusgraph-users/topic/88046694
• Expected Behavior: build with success
• Current Behavior: failing tests during build

Steps to Reproduce:

• unzip binary distribution
• cd examples
• mvn clean install # as prescribed in the examples/README.md

Workaround for using examples: mvn clean install -DskipTests

I think it would be a good idea to look into the examples. I don't had run them over some period of time.
