Vote cycle should be refreshed based on calls to the /votes endpoint

It should definitely reset based on calls to /votes. Couple reasons:

• If nobody is making calls to /votes, nobody is on the website voting and the robot shouldn't be doing anything. "If a tree falls in the forest..."
• One should be able to work on the front-end without a real robot calling the endpoint
• Avoids race conditions where the client and robot's polling is slightly out of sync. The votes endpoint will always have accurate information regardless of the behavior of the robot.
