In inventory API queries, stock table is already selected, and we want the query parameters to be applied on this stock table, whereas default related keys would add stock table one more time

- add payment_request
- also index non accountable movements

to get rid of movement table dependancy

tickets are also in delivery table

InventoryListBrain does not need a getQuantity method which returns something
else that the total_quantity on this brain, this is just confusing (and using
movement table)

The idea is to use Inventory API instead.

Also, movement with 0 price where ignored by omit_asset_increase /
omit_asset_decrease

To migrate, run:
alter table stock add column payment_request_uid bigint unsigned after funding_uid, add index payment_request_uid (payment_request_uid);
alter table inventory_stock add column payment_request_uid bigint unsigned after funding_uid;

To migrate, run:
alter table stock add column funding_uid bigint unsigned after payment_uid, add index funding_uid (funding_uid);
alter table inventory_stock add column funding_uid bigint unsigned after payment_uid;

This hurts performances a lot.

... instead of relying on automatic migration.
