Batch Stock Items, having serial number can't be moved without inserting Serial Number (#11792) (#11813)

* if doctype is batch, add extra information to args

* automatically fetch serial numbers if possible

* take advantage of changes in make_stock_entry

* code clean up

* PEP 8 compliance

* fix bug that clears serial number
