Straight-forward fix... appends diagnosticInfo rather than save the newest reference.

> HADOOP-1158 (scheduled for 0.15.0) introduced a bug where sometimes the task's diagnostic's
messages sent via {{TaskUmbilicalProtocol.reportDiagnosticInfo}} are lost. This is due to
them being not being saved properly and being overridden in {{TaskStatus.statusUpdate}}, simple
fix is to append the prev  diagnostic message.
