test mode in apps.py

From my limited understanding of the code in apps.py, it looks like this app will behave differently when I run my test suite in my project. i.e. it wont re-connect the signals, but will instead set up csignal and csignal_another which appear to be test data for this app, and not useful for testing in my project.

If so, it seems there is going to be some difficulty with testing if I need to fork and edit apps.py to get it working.
