This fixes an error when loading the diff viewer on release-5.0.x (and

master). Devtools were showing an error that the DiffViewerPage

constructor wasn't a constructor. The issue here seems to be a change in

the way that the newer babel deals with function shorthands inside of an

object. Whereas before it was translating constructor() {...} to

constructor: function constructor() {...}, it now leaves them as-is.

In most cases this works fine, but it seems like browsers are treating

the constructor name specially (since it's a reserved word and used

for classes). Explicitly using the older object attribute syntax fixes

this.

      Fix the diff viewer JS with modern babel.
      
This fixes an error when loading the diff viewer on release-5.0.x (and
master). Devtools were showing an error that the `DiffViewerPage`
constructor wasn't a constructor. The issue here seems to be a change in
the way that the newer babel deals with function shorthands inside of an
object. Whereas before it was translating `constructor() {...}` to
`constructor: function constructor() {...}`, it now leaves them as-is.
In most cases this works fine, but it seems like browsers are treating
the `constructor` name specially (since it's a reserved word and used
for classes). Explicitly using the older object attribute syntax fixes
this.

Testing Done:
Created a review request with a diff and was able to successfully load
the diff viewer page.
