Triggered by [Bug 702340]
When we try to search a composite expression like:
[( 'ourfoo.subfoo', '=' , True) ]
.. where subfoo is a function field of the model ofourfoo field,
the framework will call subfoo.search([('subfoo','=',True)]).
The latter shall return a domain expression that will restrict
the search on 'ourfoo'.
When the returned expression is empty, meaning "match all", the algebra
on the parent expression would come up with an invalid [..., '&', ( 1, '=', 1) ]
sequence.
