Supports loading of word files with images added on OneDrive

[pinekta]

Description

Add images by editing Word in OneDrive and download Word files locally When loaded with PhpOffice\PhpWord\IOFactory::load Fixed a bug that caused PhpOffice\PhpWord\Exception\InvalidImageException.

If you unzip a normal Word file with zip /docProps /word /_rels Image files are in the directory It is saved as /word/media/xxx.png.

However, if it is a file with images added with OneDrive /docProps /media /word /_rels It is stored in the media directory of the directory called In getRels of PhpOffice\PhpWord\Reader\Word2007 Since it is assumed that the image exists in the /word/mediadirectory, The image in the/media` directory could not be read and an error occurred.

for that reason, If a directory has a "/" at the beginning, it has been modified to refer to that directory.

Fixes #2245
