Fix logging so we can see what happens in the remind case

We check to see if a user has valid trips in the past 7 days before we send
them a reminder
(7034479).
However, all the related messages are displayed using `logging.debug`. Because
of the additional imports, logging is configured to WARNING, so they are never
displayed.

And in the case where there are no users with recent trips, this results in
insufficient logging to determine what happened.

- Changing the logging configuration location
- Changing the log level to INFO
- Bumping up some useful logs to INFO

Testing done:

Before the change

```
Found configuration, overriding...
Activating the environment...
Run trip labeling reminder...
Config file not found, returning a copy of the environment variables instead...
Retrieved config: {'DB_HOST': '...', 'DB_RESULT_LIMIT': None}
Connecting to database URL ...
WARNING:root:Push configured for app .... using platform firebase with token ... of length 152
```

After the change

```

Retrieved config: {'DB_HOST': '...', 'DB_RESULT_LIMIT': None}
