Swap around generic argument ordering in InvoicePayer for bindings

The bindings generation really should support generic bounds other
than Deref::Target in where clauses, but currently does not. To
avoid needing to add support during the current release process,
we simply swap around the arguments to move them to the first <>
instead of the where.
