Update field names so that config values can be picked up succesfully

@bricesanchez Hiya! -- was this released in 4.0.3?

[robbyrussell]

We ran into a problem upgrading a Rails 4 Refinery site to Rails 5 and bumping up Refinery in the process with the S3/Dragonfly configurations. We found the fix for this would resolve our config problem but wasn't in latest Rubygem releases. We're tracking 4-0-stable for now

@robbyrussell curious.. maybe I didn't release it properly 😭

By the way thank you so much for Oh My Zsh!

🤦‍♂️ I know what's going on. This code belongs in the refinerycms-dragonfly gem, and that hasn't been released with a new version. I'll push version 1.0.1

@robbyrussell it's released as refinerycms-dragonfly 1.0.1 - please let me know how you get on
