[FIX] stock_orderpoint_origin: Empty procurement

[SirPyTech]

If there is no procurement in a source document, the following is raised:

ERROR devel odoo.sql_db: bad query: INSERT INTO procurement_group_purchase_order_line_rel (purchase_order_line_id, procurement_group_id) VALUES (24, 5), (24, false) ON CONFLICT DO NOTHING
ERROR: column "procurement_group_id" is of type integer but expression is of type boolean
LINE 1: ...ne_id, procurement_group_id) VALUES (24, 5), (24, false) ON ...
                                                             ^
HINT:  You will need to rewrite or cast the expression.

I also change the source_group_ids value so that it's a recordset, like the other *_ids values in procurement.values (see for instance https://github.com/odoo/odoo/blob/6aca71c9522b3be5b221847e8b005f233d3ea872/addons/purchase_stock/models/stock.py#L246) because the error was actually triggered in

stock-logistics-orderpoint/stock_orderpoint_origin/models/purchase_order.py

Lines 36 to 38 in eebb6d3

	groups = values.get("source_group_ids")
	if groups:
	vals["source_group_ids"] = [(4, o.id) for o in groups]

when there are no procurements, groups is [procurement.group()], so a [(4, False)] is added, and then the above error is triggered when converting that to a query.
