lists not showing up on user edit form, unless *all* of a user's roles may subscribe

I was noticing an issue where lists weren't showing up for some users, if some of their roles were configured as able subscribe to this list while others were not. This is my first time using the module, but I was expecting it to work so that if a user had any role that was allowed to subscribe to a list, that list would appear. On a test site, I confirmed that was the behavior in the 6.x-1.2 version of the module.

The following patch fixed the issue for me on the 6.x-2.0-beta8 version of the module.
