As discussed in #247 the Java-clients samples contain unit-test code that is not generated but that is just added and executed by our CI.
This PR restores the tests that were removed with c8c316e4.
Because we want to be able to recreate samples
from scratch, the manually written files are added to the CI/samples.ci
folder and copied to the samples
folder at the end of the *.sh
script.
