Title: Add development time dependencies on minitest and test-unit to gemspec

In the Cygwin environment, the `minitest` and `test-unit` gems aren't bundled with Ruby so a `bundle exec rake install` fails.

The commit in this PR adds these as development dependencies so that bundler can install them if they are missing.
