fixed new relic app name

The app name wasn't displayed correctly on the new relic dashboard.

Although `NEW_RELIC_APP_NAME` was set in `production.py`, the variable was not loaded *before* the newrelic agent was called.

Since the new relic agent is loaded at a very low level, NEW_RELIC_APP_NAME has to be set before django settings are imported.
