When an inventory is canceled, the user is able to edit its locations
and products fields. So, if he/she does and then restart the inventory,
it can have some lines who don't match these fields.

Now when an inventory adjustment is canceled, we delete all its lines.
Its lines will be recreated when the inventory adjustment will be
restarted. Thus, lines will always corresponding to their inventory
`location_ids` and `product_ids`.
Also, a confirmation popup was added to ask if user really want to
cancel the inventory when he/shes clicks on the cancel button (to avoid
users delete their on going inv. adj. by miss clicking).
