The implementation of `__len__` & `__nonzero__`
were not defined for the py types `wrapping_dict`
and `wrapping_list`.
For instance, this prevented an empty list
to be considered as `False` in domains
evaluated by the web client.
e.g., in the automatic partner merge wizard,
the domain
```
[('id', 'in', partner_ids and partner_ids[0] and partner_ids[0][2] or False)]
```
is used.
When the `partner_ids` list was empty (meaning the "partners to merge" list
was empty in the wizard), it wasn't considered as
`False`, and it therefore attempted to get
`partner_ids[0]`, which resulted to a crash, as
the list was empty.
