Add a comment about what this does please.

Done.

What about the other way around - first it becomes supervised, then the sync
data arrives? That should be the more common case, so can we add another test
for that?

Done.

Also check that is has the installed_by_custodian flag?

[mamir, 2016/06/13 11:30:16]

Done.
