Bad Permissions

This plugin demonstrates how a ceratin permissions setups can accidentally block access to the entire backend. octobercms/october#1180

It appears that the backend is selecting the blocked page as the default, and therefor making the rest of the backend inaccessible. Even if I try to navigate to a different controller manually via typing "/categories" into the URL, I am immediately redirected back to the page I don't have access to.

Setup

1. Install the plugin
2. Create an administrator who has blocked access to "Posts", but does have access to "Categories".
3. Log in with the new administrator
