[#4226] Added test reproducing issue

- calling `allow($role)` after a resource exists should grant that role
  all privileges on all resources.

- Prepend `null` to the list of resources when `null` is passed as the
  resource to `allow()`/`deny()`, ensuring that `allPrivileges` gets
  updated correctly.
