Fixnum is deprecated warning under Ruby 2.4.0 and Nokogiri 1.6.8.1

[memoht]

Upgraded to Ruby 2.4.0 last night and upon launching app in development was greeted with the following in the console: nokogiri-1.6.8.1/lib/nokogiri/html/document.rb:164: warning: constant ::Fixnum is deprecated

Thought this was solved in #1545 but seeing a redx in the commit history for this merge, so guessing something still isn't resolved.

Using: macOS Sierra 10.12.2
App is using: Rails 5.0.1

This is already fixed on the git master branch and will be part of the next release. The red X is only about a failed test, but the PR #1545 is merged nevertheless.
