travis: Do not upgrade gem any more

This lets the build timeout:

```
Installing RubyGems 3.1.1
  Successfully built RubyGem
  Name: bundler
  Version: 2.1.0
  File: bundler-2.1.0.gem

bundler's executable "bundle" conflicts with /home/travis/.rvm/rubies/ruby-2.4.6/bin/bundle

Overwrite the executable? [yN]
```
