Adjust build.xml to run JaCoCo coverage when running unit tests when

flag coverage.enabled is set to true, download necessary jars, add jacoco:coverage
to junit targets and a testcoveragereport target which produces the coverage report.
Also fix a test that is affected by JaCoCo and add slightly more coverage in another test.
