[FIX] stock: Display translated picking description in delivery slip

Issue

	- Install English and French languages
	- Create a customer contact and assign french as his language
	- Create a product with correct names in both languages.
	  For example 'French product name' and 'English product name' for easy reference.
	- Create an inventory transfer with the french customer as contact
	- Add the product that you created
	- Print > Delivery Slip

	The report will show in the lines:
	"""
	French product name
	English product name
	"""

Cause

	Getting product description without checking partner language.

Solution

	If partner is set, get product description with partner language in context.
