Before this commit, doing expression.OR() with only FALSE_LEAF would
yield [] which is equivalent to TRUE_LEAF and is therefore not correct.
The same happened (to a lesser extent) with expression.AND() within an
expression.OR(), since the former would return a [] which would be
ignored by expression.OR().
See tests for a clearer view of the use cases.

We sometimes use in Odoo a One2many field with an inverse Integer
field instead of a usual Many2one.
This allow for example in several instances to have a "Many2one" which
can be reference from several models, eg:
Model Ranking:
name = String field
res_id = Integer field
res_model = String field
Model Toy:
rank = One2many [inverse: Ranking -> res_id]
[domain: res_model == Toy]
Model Tool:
rank = One2many [inverse: Ranking -> res_id]
[domain: res_model == Tool]
This enable us to have a shared feature between otherwise unrelated models.
But there was several issue when searching on these One2many:
1) if the Integer Many2one was not stored (eg. it came from an inherits) on
the searched model, this could lead to an error.
2) when we searched:
- by IDs (rank in ['55']) with at least one id not respecting the domain
- by IDs with a negative operator
- with a negative operator on unfound string (rank != "no rank has this")
- with a false value (rank = False)
we would not apply the One2many domain (eg. res_model == Toy) and thus
possibly getting Toy 3 errenously because a Tool 3 was found without
the domain being applied.
This fix modify the search on One2many and for:
1. if the inverse is an Integer not stored field instead of Many2one
manage it.
2. if the field is an Integer field instead of Many2one and there is a
domain on the One2many: apply the domain on the inverse model found.
So only some search on One2many with a domain whose inverse field is an
Integer could be impacted.
This would also be nice to have for all One2many with a domain but the
probability of it being useful versus risk for performance is not judged
high enough.
