Purpose
=======
The method named "action_invoice_create" in the sale_order model did not make sense:
- this method is not an action (it returns the ids of created invoices)
- it is not used as an action on any xml buttons
- it has no reason to be private
This was probably a "real" action somewhere in the past but now it's just too confusing.
(The method in repair.order was also renamed for the same reasons).
