The usage of ``grouped_slice`` without size is deprecated since `=
ANY(ARRAY[%s])` is used for PostgreSQL and SQLite is used only for tests.
The ``Database.IN_MAX`` is replaced by ``backend.MAX_QUERY_PARAMS`` which is a
more accurate limit of the backend.
The SQLite limits is indeed SQLITE_MAX_EXPR_DEPTH so we use a empirical value.
By using list_price_used we are sure to have a list price in the company
currency so there is not need for conversion.
Also list price of a product can be empty so we should not try to round it.
Closes#13110
Since e35820296f3a, sum_tree is use to compute project total but it requires
to have a default value for parents that are not in the list of instances.
Closes#12305
