Double store credit refunds when a error is received before redirecting to the buckaroo checkout.

[leonhelmus]

System requirements:
Adobe Commerce: 2.4.6-p4
php 8.1
module buckaroo/magento2: v1.46.1

Settings
Working buckaroo account
fill in the following settings:
buckaroo_magento2/account/secret_key
buckaroo_magento2/account/merchant_key

Certificate is not added (buckaroo_magento2/account/certificate_file) reason why is that buckaroo gives back an error before it redirects you as a customer to the buckaroo checkout.

ideal is enabled on test account

Steps to reproduce

• First create a customer where you add store credit (magento_customerbalance).
• Than add a product which you can pay of partially or full with store credit.
• Than it will trigger the error "No Buckaroo certificate configured.". (this could be any error received from buckaroo which could cancel the payment)
• In magento the order has been processed even though this error was given back.
• I get twice as much store credit back.

Expected result

• I get my store credit back, but not doubled.

Actual result

• I get two times as much store credit back.

Additional info
If this function (\Magento\Quote\Model\QuoteManagement::submitQuote) receives an error after the order has been created Magento will rollbackAddresses using this function: \Magento\Quote\Model\QuoteManagement::rollbackAddresses.

This than triggers the dispatch the event sales_model_service_quote_submit_failure which in turn invokes this observer:
\Magento\CustomerBalance\Observer\RevertStoreCreditObserver::execute

Afterwards on the same event Buckaroo has this event:

    <event name="sales_model_service_quote_submit_failure">
        <observer name="buckaroo_failed_quote_order" instance="Buckaroo\Magento2\Observer\HandleFailedQuoteOrder"/>
    </event>

Which triggers a cancellation of the order which triggers this function (\Magento\Sales\Model\Order::cancel) Which adds the following event order_cancel_after which triggers the same observer again:
\Magento\CustomerBalance\Observer\RevertStoreCreditObserver::execute

I also added this bug to the magento issues since you could also say this is an issue of magento.
