#1537: Continuations fail to revert all registers to the correct state

When the attached code is run, it outputs "foo\nfoo\n". The second foo
should, in my opinion not be there. When the continuation to backtrack in
`choose()` is created, `val` has not yet been assigned a value, and since
`choose()` doesn't return a value on the backtrack (an intentional bug, to
expose this behaviour) it should be in the same uninitialised state it was
when the continuation was created.
