Bug 21747: Use Koha::Account:: routines in UpdateFine

Set to use Koha::Account->add_debit and Koha::Account::Line->adjust

Known Side Effect: The format of the FinesLog, if enabled, is changed
after this patch. Prior to this patch the $actionname was left undefined
and the $infos field contained the string:

`"due=".$due."  amount=".$amount." itemnumber=".$itemnum`

After this patch, the logs are more consistent with other FINES logs,
with an $actionname of 'CREATE' or 'UPDATE' and the $infos field
containing a Dumper of fine data.
