I noted your comment about having `toggle` as a method directly on `ExpandableProfView`, but it looks like we can assume that if `!this.firstExpanded` we can just call `this.expandReviews` instead of `toggle` since we already know the reviews are collapsed.

This also prevents others from in the future calling `toggle` directly without first checking whether or not `this.firstExpanded` is true or not - they could bypass `loadReviews!`
