Fix wrong reference in setAttribute method of order document model

This fix changes the reference, which is used to set the one-to-one relationship between the order document and its attributes. In the attribute field annotation "document" is used as the mappedBy value, while in the "setAttribute" method the reference "orderDocument" was used. This commit changes the latter to "document", to make the one-to-one association work.
