Hitting back button from random word page goes back two pages

[danielrw7]

For example:

• Go to Project Goals
• Click on WORDSET logo (now at the home page)
• Click on "Give me a random word to improve!"
• Click back
• You now are all the way back to the Project Goals page, not the home page

I have this issue on Chrome (45.0.2454.93) and Firefox (42.0a2)

history.length isn't changing between the homepage and the random word

The "Vote on a proposal" button works correctly (the back button takes you to the home page).

I believe your pull request fixes this.
