Changes included this pull request?

• Extracted candidate rendering logic. Moved rendering to new functional component, OneOfficeCandidateList
• moved logic for determining which candidates to render into the getCandidatesToRender method. This method ensures that only the required number of candidates is passed down to the OneOfficeCandidateList.
• In this refactor, I am having an issue with the supportStore. After selecting Support for a candidate and then refreshing the page, the Support for that candidate disappears. However when selecting oppose, it remains after refreshing the page.
