Subject: [PATCH] Work around JRuby failing on bundle install

Still haven't figured out the _why_, but bundle install fails on JRuby head and 9.4. Making sure to install psych with `gem install` first makes the problem go away.

I'll debug this out of band, but for now this makes all our CI builds succeed again.
