BatchRequestItem use absolute url path instead of relative when, causing "Ressource not found" 400 error

Describe the bug

Here is my code :

batch_requests = BatchRequestContent()
for message_id in message_ids:
  query_params = MessagesRequestBuilder.MessagesRequestBuilderGetQueryParameters(
      select=[
        'id',
        'conversationId',
        'internetMessageId',
        'subject',
        'body',
        'bodyPreview',
        'from',
        'toRecipients',
        'ccRecipients',
        'bccRecipients',
        'receivedDateTime',
        'sentDateTime',
        'internetMessageHeaders',
        'isRead',
        'isDraft',
        'importance',
        'hasAttachments',
        'categories',
      ]
    )
    request_configuration = RequestConfiguration(
      query_parameters=query_params
    )
    request = service.me.messages.by_message_id(message_id).to_get_request_information(
      request_configuration=request_configuration
    )
    request_id = str(uuid.uuid4())
    batch_request_item = BatchRequestItem(id=request_id, request_information=request)
    #   batch_request_item.url = batch_request_item.url.replace('https://graph.microsoft.com/v1.0', '')
    batch_requests.add_request(request_id=request_id, request=batch_request_item)

Without the line I've commented, it causes a 400 "Resource not found for the segment 'https:'".
I figured out the problem by looking at your code.

I guess it is not the behavior as you intended.

Expected behavior

The server answer a code HTTP 200

How to reproduce

1 - List message ids from Outlook
2 - Try to get the email content in batch

首先使用 Python 示例跟踪 BatchRequestItem 和 BatchRequestContent.add_request，然后检查批处理操作的请求 URL 是如何构造的。使用 Outlook 消息批处理复现来验证行为，并确认提交的项目使用相对路径，且无需 workaround 即可收到 HTTP 200。
