Remove the optimization of the `product_tmpl_id` related fields which
needs a upgrade to work without any issues.

This reverts partially the commit
4c627651.

Find a other for the stable to optimise the forecasted report of product
template:
When the `product_tmpl_id` is in the domain of a read_group, it will
be replace by a equivalent clause with `product_id` instead to avoid
any sub-query which didn't help the postgreSQL planner.
The performance decrease but it still acceptable compared that before
the revert fix (test with one template with 256 variants in
a DB with 40K products and 100K moves, 1K locations, etc)
- Revert fix (which need a upgrade): 75 ms
- new fix (no need a upgrade): 130 ms
- without any fixes (before the revert fix): 500 ms (also have a bigger
scale penalty)
