[Fix #25] Fixing validation date offset

Actually, validation dates on transactions are stored in the French
timezone but in Odoo the timezone attended is UTC. A minor fix is needed
in the _payfip_evaluate_data method for passing the timezone into a UTC
one.

Migrate all previous validation dates to fix the timezone issue.
All transactions are processed in chunk of one hundred.
