broken xls writer: lost EMF embed image

[SailorMax]

This is:

• a bug report
• a feature request
• not a usage question (ask them on https://stackoverflow.com/questions/tagged/phpspreadsheet or https://gitter.im/PHPOffice/PhpSpreadsheet)

What is the expected behavior?

Readable XLS file with embed image.

What is the current behavior?

If open in Excel, XLS file with broken image.
If try to read it by PhpSpreadsheet, we've got:

Uncaught Error: Call to a member function getBlipType() on null in lib\PHPOffice\PHPSpreadsheet\phpoffice\phpspreadsheet\src\PhpSpreadsheet\Reader\Xls.php:1137

$BSECollection is empty array.

What are the steps to reproduce?

<?php

require __DIR__ . '/vendor/autoload.php';

$fileType = 'Xlsx';
$fileName = __DIR__.'/imgBook1.xlsx';

// Read the file
$objReader = PhpOffice\PhpSpreadsheet\IOFactory::createReader("Xlsx");
$objPHPExcel = $objReader->load($fileName);

$output_type = "Xls";
$output_file_name = __DIR__.'/output';
$objWriter = \PhpOffice\PhpSpreadsheet\IOFactory::createWriter($objPHPExcel, $output_type);
$objWriter->save($output_file_name);

$outputReader = PhpOffice\PhpSpreadsheet\IOFactory::createReader($output_type);
$outputPHPExcel = $outputReader->load($output_file_name);

imgBook1.xlsx
Sample Xlsx with 1 embed EMF picture.

Which versions of PhpSpreadsheet and PHP are affected?

sources from 13.11.2017

Please provide a Minimal, Complete, and Verifiable example of code without relying on an external Excel file.

"lost EMF embed image"
Create new document in any editor, put in it EMF file and convert it to xls via PHPSpreadsheet.
How I can write example without external file? EMF file from where to get?
I did easier - prepared sample xlsx.

Looks like not critical for everyone. Can be forgotten.
May be I will try to fix it later by myself.
