Regression test for ground-truth jobs from video

[archibald1418]

This provides coverage for fix #9095

Motivation and context

How has this been tested?

• Generate new task from existing videofile with 3 frames
• Create new ground truth job, picking 1 frame (the bug manifests when frame index is greater than frameCount)
• Go to job, play the frames. No crashes should happen

feature test ground_truth_jobs.js already contains regression tests, so this test updates that. A separate describe block is added with separate hooks to generate a gt-task from video
