Run `bundle install` to install missing gems.

Running bundle install solves nothing, so I tried:

$> rm test/Gemfile.lock
$> bundle install

which succeeds, and then:

$> terraspace test

=> cd test && bundle exec rspec

Are there additional configuration steps or missing dependencies required before running the test?
