Taus 489e1e94e4 Python: Prevent bad joins
Adds a few unbinds to prevent bad joins from occurring.

Firstly, we never want to join `StepSummary::step` with
`TypeTracker::append` on `summary` as the first join, as the resulting
relation is absolutely massive. So we decouple the two occurrences of
`summary` by unbinding each of them.

Secondly, in some cases the node we're stepping to (`nodeTo` for type
trackers, `nodeFrom` for type backtrackers) will get joined eagerly
with the typetracker one is defining, and again this produces an
uncomfortably large intermediate join. A bit of unbinding prevents this
as well.
