Transfer/cheque number on sales tax/VAT payment record not transferred to bank transaction record

[Ashley-Butcher]

Hello,

When adding a VAT/sales tax payment and specifying a transfer/cheque number, this identifier is not transferred onto the resulting bank transaction and instead only appears concatenated to the VAT payment type.

Repro steps:

• Billing/payment -> Taxes/Special expenses -> VAT
• New sales tax payment
• Enter details, including a transaction number
• Check bank transaction, transfer/cheque number is not shown

Version: Confirmed to still be impacting 12.0.2, however this has been an issue for years (certainly version 10.x and before)
OS: Confirmed on Doliwamp (windows 10), also Debian buster
Web: Apache with doliwamp packages, Apache 2.4.46
PHP: PHP with doliwamp packages, PHP 7.3.19
Database: MySQL/MariaDB with doliwamp packages, MySQL 5.0.45

Sorry if this is a dupe, I couldn't find it. :)
