Improve application logging out put for error messages

[abraunegg]

• When enabling system logging to a log file, the actual ERROR line is forced to a new line in the application log. The reason for this is the \n prefix in the error message, which was in place so that when performing CLI logging or systemd logging, the error message would be displayed clearly. This change removes the \n from the actual error message, but inserts a newline before the error message is displayed - thus keeping the application runtime look and feel, but improving the application log output.
