Comment:
What you're seeing is the result of the signal handler getting installed
twice. This is due to a quirk of Python's model importer; if one file has
"from foo.bar import whiz", and a second file has "from bar import whiz",
the whiz module will be imported and processed twice, as long as the
PYTHONPATH supports finding both locations.
In this case, I'm guessing that two locations are settings.INSTALLED_APPS
and tests.py differ - one has the full project path, but the other only
has the application name in the import. As a result, the module is getting
imported twice, and the signal is getting installed twice. If you modify
the import paths to be consistent, the problem will go away.
