[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...

[REM] unecessary calls to list()

* Either further operations don't really care (e.g. ``str.join`` takes any
  iterable)
* Or they do their own seq (``browse`` calls ``tuple()`` on iterable params)

[FIX] portal: avoid errors during autovacuum

When the cron for autovacuum runs, the osv_memory objects are deleted. The portal.wizard.user object has a required field (wizard_id) linked to another osv_memory object (portal.user) which causes a traceback when the cron tries to delete portal.user object before the portal.wizard.user. opw 609918
