[FIX] purchase: fix reference update at onchange

Add two PO with references 'XY' and 'Z' to a vendor bill.
The reference is computed as 'XY, Z' (with ', ' as separator).
Add a PO with reference 'X', the reference becomes 'X' instead of 'XY, Z, X'.

There are two variables that may not be defined (vendor_ref and self.reference),
and specifically the case where a reference is the prefix of another one is not
correctly dealt with.
