Completly move to Github Actions (#763)

* Run tests on ruby 2.7

* `ruby/setup-ruby` comes with the right bundler

* Add head versions to github actions file

* Add RUBYOPT to github actions config

* Only run the master branch on push

Just like in TravisCI.

* Remove TravisCI in favor of Github Actions

* Github Actions should be fast enough
