File logging in production

[sheshankkodam]

When working locally with the configuration below, file logging works. However, when created a release using MIX_ENV=test mix release --env=prod and running the application using _build/dev/rel/hutt/bin/hutt start command file logging does not work

Config.exs
-----------
 config :logger, :hutt,
        format: "$date $time $metadata[$level] $message\n",
        path: "log/hutt.log",
        level: :info`

The logs worked after updating `config/test.exs' with following changes

 config :logger, :console, format: "[$level] $message\n"
