Fix Trac #5263: bug in chooseExternalIds
An identifier used in an unfolding wasn't getting marked
as an external Id, which caused subsequent chaos.
In understanding and fixing this I refactored some of
chooseExternalIds. As a side benefit, the order in which
it enumerates the free variables of the IdInfo is now
deterministic (this was a to-do before).

Making a test case is awkward, so I gave up.
Anyway, can you try now?
Simon
