Project dataexport showing no track skeletons

[RuDevKu]

Actions before raising this issue

• I read/searched the docs
• I searched the existing issues and did not find anything similar.

Steps to Reproduce

Manual reproduction

• Create a new project and a skeleton
• Create a new task, job, few images
• Create a skeleton track on first image
• Create a skeleton shape anywhere on any image
• Export the project data - either in CVAT Image 1.1 or in COCO Keypoints format
• Export the job annotations - either in CVAT Image 1.1 or in COCO Keypoints format

Prepared sample

• Import the minmal sample IssuesProject.zip and export as above

Expected Behavior

All exports should show all points of either the track or the shape skeletons

• Job annotations do exactly that
• Project dataset shows zero box sizes, zero keypoints and num_keypoints == 0

Possible Solution

I'd assume when exporting the project data dangling tracks are not evaluated per image.
Thus calling the same routine(s) as for the jobs should do the trick.

Context
