Consider the following setting:
- on model A, field F is computed, stored, and depends on field G
- on model A, field one2many G to model B, with inverse field H
- on model B, field many2one H is inherited (_inherits) from model C
- on model C, field many2one H is stored
When adding records of model B, the field F must be recomputed. In order to
determine which records to recompute, one searches model A with a domain like
[(G, 'in', ids)]. In expression.py, this is resolved with an SQL query like
select H from B where id in {ids}
This query fails, since the field H is not stored in model B. This happens in
general if H is not stored (it may be any computed field). In that case, one
should instead browse records from B, and read field H through the ORM.
A test case has been added: it introduces a many2one field in a parent model,
and a one2many field using the inherited many2one on a child model. The test
checks whether one can search on the one2many field.
