[FIX] l10n_ch_scan_bvr

In these following BVR strings:

0100000830759>102000304752570109843010005+ 010505863>
0100000667157>115000278565310109843010006+ 010505863>

what's is parsed as 'bvrnumber' doesn't really represent a valid bvr_adherent_num.
In this case a filter domain based on acc_number is needed. Further, a postal account that refers to a bank is uniquely identified by (beneficiaire + bvrnumber).
