[TD] Mute some javac tests or update their testdata

There was a refactoring of AbstractDiagnosticsTest in 9052ef06 which
  contains bug that `setupEnvironment` for AbstractDiagnosticsTestUsingJavac
  was not called, so for last year tests `UsingJavac` had no difference
  with usual diagnostics tests which causes some contradictions in test data
