BP-4175 Fetch buckaroo table through a function to accomodate prefixes if there are any

[wahidnory]

Issue

One of our clients had issues with xcore synchronisation, it seemed that all the orders were failing to sync.
After looking through error messages I've found out that there's a join that's failing pretty bad and causing a 500 error.
The error in question

#19 {main} {"exception":"[object] (Exception(code: 1146): Report ID: webapi-67a385357870c; Message: SQLSTATE[42S02]: Base table or view not found: 1146 Table 'REDACTED.buckaroo_magento2_giftcard' doesn't exist, query was: SELECT `main_table`.*, `buckaroo_magento2_giftcard`.`label` FROM `a4h_buckaroo_magento2_group_transaction` AS `main_table`

Currently

It seems that the helper function is trying to join on a table but without any prefixes. Just plainly the buckaroo_ tables.
This is a problem in one of our clients installation.

Fixed

To solve this I've adjusted the fetching through a Resource Model.

Please consider this PR as a hotfix, it shouldn't break any functionality.

Thank you in advance.
