[FIX] stock: duplicate foreach keys in replenishment history

Before this commit:
The key used in the foreach, `line`, is an object, which is converted
into the following string `[object Object]`, resulting in duplicate keys
and display a traceback when changing the supplier on an orderpoint.

After this commit:
The key used is `line.name`, which is a unique date across the dataset,
preventing any duplicate keys.
