A domain with a negated thruty leaf raises an exception here
https://github.com/odoo/odoo/blob/835197e48fbbee1c8ac35d52287537fa6f0bdd36/odoo/osv/expression.py#L614
due to
https://github.com/odoo/odoo/blob/835197e48fbbee1c8ac35d52287537fa6f0bdd36/odoo/osv/expression.py#L670
and the fact that `FALSE_LEAF != (1, "!=", 1)` and `TRUE_LEAF != (0, "!=", 1)`
Current wrong behaviour:
```
>>> distribute_not(['!', TRUE_LEAF])
[(1, '!=', 1)]
>>> is_leaf((1, '!=', 1))
False
```
This issue was noticed when adapting domains for fields that have been
removed during migration. Example (extract of) traceback:
```
