[bugfix] html points to dashboard.entry.js instead of jsx

[mistercrunch]

@georgeke @ascott , I needed to change that to get things working after I rebased a branch. I'm confused as to how it worked on your side @georgeke, maybe different version of webpack have different rules as to generating a .js vs .jsx?

Coverage remained the same at 81.114% when pulling b248cec on mistercrunch:fix_dashboard_jsx into 18b8e6f on airbnb:master.

@mistercrunch when I was developing dashboard.jsx the webpack was outputting js files (filename: '[name].entry.js') so this change wasn't needed. I think the correct fix may be to switch the output files back to .js. It was my understanding that our built files should be pure js, I'm not sure on why they are .jsx?

@ascott do you have any thoughts on this?

[mistercrunch]

On my side it now builds to jsx.

webpack 1.13.0
$ node -v
v5.10.1
$ npm -v
3.8.3

It seems to be the same (jsx) on the Travis build

A recent pull request from x4base also made this fix. Since master is broken as far as travis would be concerned if it tested js, I'm merging this.
