Description
When exporting annotations in the COCO format, a backward slash appears in the file_name field of the exported COCO JSON file.

To Reproduce

Steps to reproduce the behavior:

1. I had a pre-annotated COCO json file (generated by the model), and I wanted to refine the bounding boxes.
2. I followed the steps mentioned over here, and I was able to import the annotations.
3. I have set 'Local files' as my Source storage type, and my absolute path is: /home/roshan/images
4. Now, when I export my tasks in the COCO file format, the project gets downloaded and I get the images and result.json in my Downloads folder.
5. [ISSUE: ] In the result.json file, the file_name field is in the following format: /home/roshan/images/image_name.jpg

Expected behavior
The file_name field should be in this format: /home/roshan/images/image_name.jpg

JSON requires that special characters be escaped to render properly. The \/ is an escape sequence that represents /.
