WebDriver tests take forever

[lambdabaa]

Our webdriver test suite

• purges the database,
• starts meteor (and mongo),
• loads database fixtures,
• starts firefox,
• runs test code,
• and posts coverage info

For each test. It takes a long time. We need to parallelize tests or otherwise speed things up so that developers can get faster test feedback.

Note that, at the start of this investigation, the test suite is taking 8-9 minutes to run on circleci.
