logging: Fix missing logging

[vinzenz]

Previously we started using logging before it had been initialized. Which resulted in leapp stopping to log for some logger names the debug output. We did not know why this happened. It turns out that fileConfig from the logging library has a parameter disable_existing_loggers which is by default set to True and will set all loggers that have existed before the call to fileConfig to disabled. Which in turn will make them stop logging of course. This patch will change this behaviour and set disable_existing_loggers to False in order to have existing loggers be still enabled.
