Fixing concurrent-ruby incompatibility with version bump

[randalldfloyd]

While trying to release v5.0.2 containing all changes up to the Ruby/Rails upgrade, it was discovered that Hyrax would potentially not build because of an issue with concurrent-ruby. This was addressed during that upgrade, so we're just cherry-picking and adding ec36aca so we can release v5.0.3.
