The view_react permission was added in https://github.com/theforeman/foreman/pull/6741 apparently in order to get a test to pass (https://github.com/theforeman/foreman/pull/6741/files#r283366317).
This permission makes no sense from a user pov - users care about resources, not about how the page is rendered.
This also leads to multiple warnings when seeding roles as they don't find a `React` resource.
