client: raise KeyError from __getitem__ (BC)

object.__getitem__ is supposed to raise either IndexError or KeyError
(depending on whether the thing is a sequence or a mapping). Before,
we would raise ValueError because that's what the context constructor
raises.

I choose to raise KeyError because IndexError felt a bit too limiting.
This does sacrifice some magic with for loops handling IndexError.
However, iteration of this object should be handled by a custom
__iter__, so I don't think this is a problem.
