Internal call to 'route_set.recognize_path' fails with multiple mounted engines

[domaindrivendev]

Consider the following application routes ...

  Rails.application.routes.draw do
    mount CareManagement::Engine => '/care'
    mount CarePlanning::Engine => '/care_planning'
  end

If you try to access a "roles_on_routes protected" route in the CarePlanning engine e.g. "GET /care_planning/resources", then roles_on_routes throws the following error:

ActionController::RoutingError (No route matches "/care_planning/resources"):
actionpack (3.2.22.2) lib/action_dispatch/routing/route_set.rb:642:in recognize_path' /opt/boxen/rbenv/versions/2.1.5/lib/ruby/gems/2.1.0/bundler/gems/roles_on_routes-b502875b3d89/lib/roles_on_routes/engine_aware_route_set.rb:31:inrecognize_path'

HOWEVER ..........

If you switch the order of mounts in routes.rb, then it appears to work without any problems

  Rails.application.routes.draw do
    mount CarePlanning::Engine => '/care_planning'
    mount CareManagement::Engine => '/care'
  end

So, it looks like both mounts starting with the same text (e.g. '/care') is causing the problem. Weird!
