Fixed bug in which logging outputs from dummy lockers were duplicated.

The issue was that the same name was given for the logger for both the DummyLocker and DummyScanZoomLocker, which meant that they actually shared one logger. This led to dupplicated outputs, probably due to multiple handlers being added to the same logger.
