Trying to use the solidus_sitemap extension, but getting lots of

ActionController::UrlGenerationError: No route matches {:action=>"new", :controller=>"user_sessions"}

type of errors. I was able to locally get it working by forking the gem and prefixing main_app on all the route helpers in solidus_defaults.rb, so like

login_path

becomes

main_app.login_path

and I can submit a PR, but wanted to know if there's a better way to fix this first if anyone has any ideas.
