[IMP] raise exception when a DB request fetches ids it was not asked for

Likely caused by a type incoherence e.g. providing an id as string when the
table uses integer ids. Postgres performs an implicit conversion from string
to integer[0], this wasn't much of an issue in the old API, whatever cache was
there would simply not be used, but because the new API's cache is part of its
behavior it has a semantic impact and can lead to infinite recursion.

[FIX] unsafe listification of weakref in Python < 2.7.4

Fixes #966

* As a preallocation optimization, ``list()`` calls ``__len__`` on its
  parameter if it's available
* Before Python 2.7.4, WeakSet has a bug[0] where ``len()`` is unsafe: it is
  done by iteration and weakrefs may be removed from the underlying set during
  the iteration

As a result, the safety feature of listifying a WeakSet to ensure we have
strong refs on all items during iteration may blow up.

Wrapping the weakset in a ``iter()`` makes ``__len__()`` invisible and ensures
we're within the IterationGuard[1].

Which now that I think about it means we *should* be able to safely iterate
weaksets in the first place and may not have needed to listify them...
