Fix issue #88: restrict_universe_context was wrongly forgetting about constraints,
and keeping spurious equalities. simplify_universe_context is correct, although it might keep unused universes around (it's the responsibility of the tactics to not produce unused universes then). Add printer for future universe contexts for debugging.
