Subject: [PATCH] [FIX] purchase: purchases button on product variants

This rev. is related to 8381d47543e998e792b9514d9e6b19635832052b

The action action_purchase_line_product_tree is used in both
product templates and product variants forms.
Therefore, the default_product_id: active_id in the context
cannot be used,
As sometimes it will active_id will be a product template,
sometimes it will be a product variant.

I believe two different window actions should be used,
instead of sharing a common one and making hacks.
Nevertheless, as we avoid taking risks in stable releases
This should be done in master.
