Raise error message from SOAP response when initialize action fails

[bebanowski]

The current error handling approach of the initalize action is to raise a generic failure message.

For example:
NetSuite::Records::ItemReceipt.initialize with #<NetSuite::Records::PurchaseOrder:0x00007f561d8717c8> failed.

This does not provide any of the useful context from the SOAP response XML which would be more helpful for debugging the issue.

For example:

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
  <soapenv:Header>
    <platformMsgs:documentInfo xmlns:platformMsgs="urn:messages_2021_1.platform.webservices.netsuite.com">
      <platformMsgs:nsId>WEBSERVICES_3479023_SB2_01222024842151163424342931_794960285</platformMsgs:nsId>
    </platformMsgs:documentInfo>
  </soapenv:Header>
  <soapenv:Body>
    <initializeResponse xmlns="urn:messages_2021_1.platform.webservices.netsuite.com">
      <readResponse>
        <platformCore:status xmlns:platformCore="urn:core_2021_1.platform.webservices.netsuite.com" isSuccess="false">
          <platformCore:statusDetail type="ERROR">
            <platformCore:code>INVALID_INITIALIZE_REF</platformCore:code>
            <platformCore:message>You can not initialize itemreceipt: invalid reference 54572740.</platformCore:message>
          </platformCore:statusDetail>
        </platformCore:status>
      </readResponse>
    </initializeResponse>
  </soapenv:Body>
</soapenv:Envelope>

Support for fetching error context from the SOAP response XML has been added to other actions, for example:

• 3b756b9
• e640196
• 70ab077

Adding similar support to the initialize action, and using the message of the first error in the SOAP XML for the InitializationError raise, would provide more useful error context for debugging.
