lisa uses current directory and does not honor the working path

[maddieford]

Working with @narrieta on waagent test automation.

We hit a bug where Lisa ignores the provided working_path & uses the current directory instead:

/usr/bin/python3 -m lisa
--runbook
--log_path <log_path>
--working_path /home/maddieford/tmp/lisa

Updating my pycharm configuration's working directory solved the issue, but this caused some confusion. Thanks
