[FIX] stock_account: reposition serial/lot table

Go to Settings, Enable "Display Lots & Serial Numbers on Invoices"
Now have a [PROD] tracking "By Unique Serial Number"
Add 5 SN
Create a Sale order for 5 units [PROD]
Delivery
Create invoice
Check portal preview

Issue : Preview will be messed up. Invoice footer will overlap the table
displaying lot/SN
This occur after 3764914c86
The element containing the total has been moved into a right column
(floating element) to show invoice business data in the left column.
The lot/SN table inheritance xpath would put it after the total. This commit
reposition the table on the left column
