Title: Two fixes to review for deploy

One avoids a hard problem where an app can apply auth w/ a made up account id (by accident even) and it results in a really confusing situation (and is probably a bad thing to allow, unless more thought and care is put into it as an actual feature).

The other is a bug @beaugunderson discovered with friends/peers where the list is sometimes incomplete randomly, because the merging process wasn't recursive and it depended on the internal ordering of the array in JS.
