Fix watch collections for the edge case that the model hasn't been set yet

[mboudreau]

When trying to watch a collection of data.candidates, the data object wasn't initialized yet and hence couldn't watch the collection. Even after data.candidates, it never showed the results.

Hm, might be because of a weird timing issues with layout CSS for width.

Was actually because of an ng-show that was correlated to the data. Couldn't find the layout offsetWidth since it wasn't being rendered. Need to figure out a workaround.

Using ng-if instead fixed it for now.
