Merge lp:~stevenk/launchpad/bpph-supersede into lp:launchpad

[Steve Kowalik]

No longer tolerate supersede() being called on unpublished binary arch-dep publications. This allows us to remove some probable foot-guns from the code, and also brings the source and binary supersede methods into closer alignment.

One assert is not enough, since we need to tolerate SUPERSEDED arch-indep publications.

As we chatted here in person, I'm not sure about the condition check you do, but I don't understand what you're trying to do here well enough to feel confident voting yay or nay. Do you mind getting someone else to look at it?
