Find assets via build_environment in Sprockets 3.

[dstrus]

With config.assets.compile set to false (which it is by default in production in Rails 5), Rails.application.assets returns nil. In that case, we can call Sprockets::Railtie.build_environment(Rails.application).find_asset in place of Rails.application.assets.find_asset.

Great! Do you think you could extract this out to a private method or something that lines 74 and 106 could also use?

Done!

Thanks a ton!
