Reset unchoked/interested state on 'end'

[astro]

Just an idea: wire instances have state bits (unchoked/interested) that have an initial default.

I'd hook on('interested') to potentially unchoke a peer, and then on('uninterested') to remove them from the list of unchokable peers. I'd do the latter equivalently on wire disconnect, on('end').

Hence the question: should we emit('uninterested') if the peer state was interested but the wire ended? Same for emit('choked')?

The changes would be minimal but the semantics would make usage easier.

This seems like a reasonable change. Done.
