Remove extra div

[lifeiscontent]

@tanem are you guys considering removing the divs now that react 16.2.0 has fragments? If you want, I can submit an additional PR for that as well.

Coverage remained the same at 100.0% when pulling be70e75 on lifeiscontent:master into c3a0e28 on atomic-app:master.

Thanks for PR @lifeiscontent but I won't be merging this in because reasons: #24 (comment). I should really create a test around this as it comes up a lot.

Good point re fragments, will check that once I get the chance to look at the newer React version, but I'd still like this module to be compat. with older React too at this point.

@tanem that's what major versions are for... E.g. Rails 5 and Rails 4 both still work, but use different versions of gems.

@lifeiscontent sure, just haven't had time to give it much thought yet. At the moment having something working and stable that's low maintenance is the goal. Will get to it at some point though.
