Try to cleanup the Gemfile... again.

The problem last time was that we removed Pry and Pry brings in CodeRay, we were
testing legacy stuff and didn't have CodeRay in our dependencies, which resulted
in those tests failing.

This also quietly announces the intention to move to RSpec by moving the old
test dependencies to ":test_legacy" and is slightly less agressive in it's
organization than before.
