Nicolas Simonds 2a446c5b6b Only add logging handlers if there currently aren't any
This corrects an odd problem where Horizon would stand up multiple
client objects, which would cause duplicate/triplicate/dozens of
repeated log lines in its log files, due to multiple identical
handlers being added to the logging object

Fixes Bug 1182678
