Switch between themes following the setting option

Thanks for the patch!
Working perfectly on my build. 8.x-1.16

I'm not sure what the rules are for marking an issue RTBC, so... will leave as is, but would love to see this go into next release so I don't have to keep patching it. Also, this seems like a bug to me. Shouldn't the module respect the 'Use the administration theme when editing or creating content' checkbox setting?
