Fix JUnit tests for logCache

The old "Applications.logs" method is keept for
compatibility and when a log stream is needed.

Adding new "logsRecent" method to access the logCache.

integration-tests "ApplicationTest.logs" and
"ApplicationTest.logsRecent" work.

Minor changes in DefaultApplicationsTest in other JUnit tests
to make them execute in Eclipse.
