on_production_server returns False for manage.py remote

[egasimus]

I'm using a Google Cloud SQL database in production, as well as a local MySQL database for development. Which database is active at a given time is determined in settings.py by on_production_server. However, when trying to run South migrations on the remote DB using manage.py remote migrate, on_production_server defaulted to False.

Therefore, on_production_server needs to take into account if the command has been run using manage.py remote.
