No loggers defined for any of our apps

One-sentence description

Anything that is logged by concrexit isn't saved anywhere, only exceptions seem to be logged, this could be due to sentry.

Current behaviour / Reproducing the bug

import logging

logger = logging.getLogger(__name__)
logger.error("Module loaded")

I tried this in an urls.py because it's always loaded, and with production settings this message is not logged. This is because LOGGING in settings/production.py doesn't define a logger for e.g. education.urls.

This can be resolved by adding a root logger like so:

'loggers': {
   'django': {
       'handlers': ['console', 'logfile'],
        'level': 'INFO',
    },
    '': {
       'handlers': ['console', 'logfile'],
       'level': 'INFO',
    }
},

This makes it so all messages that propagate to the root logger and have at least log level INFO get logged to console and logfile.

Expected behaviour

Useful log messages are logged by concrexit.
