So what happens, supposedly, is that the currently primary UID gets its self
signature first, and then the others.  As it happens, a new second begins
between that and one of the secondary UIDs becomes primary UID then because
they have newer self-signatures.  Wonderful :)

Well, I guess that fixing the primary UID through the edit interface is an
acceptable hack then (for the test suite).
