Strip bank_id's last char
Created by: tbalthazar
CSV import create duplicate entries because it relies and the bank_id
field to always be the same for a transaction, across exports.
Observations show a transaction always has the same bank_id
across
exports, except for the last char. I haven't found any documentation
about the CSV/bank_id format but looking a the duplicate entries we have
in the database and at entries from a couple of different CSV exports,
it should fix our issue.
