This commit fixes two problems:

1. When a user clicked on another page, the app would fetch the new page
data but never update because the request and response parameters failed
to match the isEqual check. This was happening because the JSON response
omitted the `nested` attribute, so there was a comparison with a `null`
value.  We fix this by scrubbing undefined values before doing the
comparison.

2. There were duplicate requests made for the environments page because
the success handler of fetchPipelines() would cause the polling
component to make another XHR request.

Ensure folders push to the top, if both have no last update, sort by
name.

The sorting algorithm should sort in the following priorities:

1. folders first,
2. last updated descending,
3. by name ascending,

the sorting algorithm must:

1. Sort by name ascending,
2. Reverse (sort by name descending),
3. Sort by last deployment ascending,
4. Reverse (last deployment descending, name ascending),
5. Put folders first.

It is done this way, as `underscore`'s sort API is very basic: simple
comparisons, sorting by ascending only.

When a user clicked on another page in the pipeline page, the following
would happen:

1. PipelinesService.getPipelines() would be called to fetch the new page
2. In the success handler, Poll.restart() would be called
3. This would invoke Poll.makeRequest(), which would fire off a new
request.

To fix this, we introduce a enable(), which will:

1. Update the request data accordingly
2. Clear the old timeout if necessary and start a new timer
