Line-item->data context not saved to line-item. Causes Rules action 'Get the referencing node from the line item' to fail.

I'm using the commerce_rules_extra module and make use of the rule commerce_rules_extra_node_from_line_item ('Get the referencing node from the line item').

Currently commerce_product_bundle module does not pass through line_item->data['context'] correctly, which causes the above mentioned rule to fail.

I've written a simple patch that corrects this oversight. See first comment.
