conf: use flask.current_app.config not in gn3.settings

The configuration in gn3.settings can (and does) get overwritten by values in
the environment variable `GN3_CONF` and any configurations passed in the call
to the `gn3.app.create_app` function; as such, this commit changes the
configuration used in the code to user the final configuration values that are
in the running application's `flask.current_app.config` object.
