Unable to create/edit role when user can't find index-patterns

[kobelb]

If the user doesn't have privileges to find the index-pattern saved-object type, then the user is unable to create/edit a role. Clicking the "Create" button will just do nothing, and not display an error message.

This can be recreated by creating a role which has the all privilege to advanced settings across all spaces, as this feature privilege doesn't grant implicit read-only access to index-patterns.
