Fix logging level when using "-lwsc=true" (KC-290)

[kihneman]

This PR fixes the logging level when using the option -lwsc=true. For some reason when this option is true, logging.basicConfig does not set the logging level according to the level parameter that is passed. The workaround is to use a separate logging.getLogger().setLevel to set the correct logging level.

On further investigation, the reason logging.basicConfig doesn't work in some situations is because of the following in the documentation:

This function does nothing if the root logger already has handlers configured, unless the keyword argument force is set to True.
