[WIP] Add jasmine to travis

[gemfarmer]

For #628
Adds the jasmine:ci to travis.

Updates jasmine tests to pass.

I generally prefer clear code over code comments because inevitably someone will change the code without updating the codes. Any way we could update this js to make it clearer / mitigate need for code comments?

[gemfarmer]

I agree that the names need some refactoring. It feels quite a bit outside the scope of this PR. Why don't I just remove the comment for now, and create a naming issue for later refactoring?

[jessieay]

that works for me!

looks like jasmine test are running on travis!! woot woot

sadly, they are failing

[gemfarmer]

@jessieay I got pulled into some EITI stuff, so I'll take a look at it today. Running rake jasmine the tests run fine, but jasmine:ci isn't accessing the mock data for some reason, so the tests are failing :(

[gemfarmer]

Update: I passed the mock data directly to the previous_winners_spec.js variable (instead of referencing it from a helper file). The issues continued to exist while running rake jasmine:ci.

So why am I getting this error (below)? jasmine:ci runs phantomjs as a headless browser, so I figured that that might be the issue. Sure enough, there are several reported issues with similar errors

TypeError: undefined is not a constructor

Closing this in favor of #659
