uploadStream uploads 0 size object when you pass an empty object to bufferSize

[tonybart1337]

• Package Name: @azure/blob-storage
• Package Version: any version up to 12.25.0
• Operating system:
• nodejs
  • version: any supported
• typescript
  • version: I'm using javascript

Describe the bug
If you pass an empty object to bufferSize parameter of uploadStream then it will upload and overwrite the object with 0 bytes, completely ignoring the input stream without any indication that something went wrong

To Reproduce
Steps to reproduce the behavior:

    const blobServiceClient = new BlobServiceClient(
      'https://REDACTED.blob.core.windows.net'
    );

    const containerClient = blobServiceClient.getContainerClient('REDACTED_CONTAINER_NAME');
    const blockBlobClient = containerClient.getBlockBlobClient('REDACTED_FILE_NAME');

    // when you pass an empty object    
    const opts = {};
    const result = await blockBlobClient.uploadStream(dataStream, opts);

Expected behavior
Throw an error that bufferSize has invalid type or any other indication that it didn't upload the entire stream
