Removed setting log4j-console.xml as default

[robvadai]

According to the documentation (https://samza.apache.org/learn/documentation/0.10/jobs/logging.html) the run-class.sh script should set the default logging behaviour in case custom log4j.xml is not previously set. The line that is now removed from run-job.sh set the default logging to use the log4j-console.xml. This prevented the run-class.sh script to set the default logging configuration.
