Webpack.logger uses wrong logger

[flippakitten]

I'm not sure why this was designed like this but when initializing the Webpacker.logger, if Rails logger is using TaggedLogging, it sets Webpacker.logger to use the Rails logger, otherwise it uses Tagged logging.

The issue is if you have a custom formatter, calling ActiveSupport::TaggedLogging.new will set @formatter to use SimpleFormatter

  initializer "webpacker.logger" do
    config.after_initialize do
      if ::Rails.logger.respond_to?(:tagged)
        Webpacker.logger = ::Rails.logger
      else
        Webpacker.logger = ActiveSupport::TaggedLogging.new(::Rails.logger)
      end
    end
  end

I've opened a PR #1311

Ran into this myself. It doesn't play well at all with other logging libraries like ougai since the tagged logger stringifies the message (which is a hash).

If anyone comes across this I ended up using SemanticLogger.
