Heatmap on scene card disappears if you move scene

[LeGrosFromage]

Describe the bug
I have many scenes with "funscript" files and am able to generate the heatmaps. The heatmaps show correctly on the scene card and if you open the actual scene itself. If you then move the actual video (and funscript) file to a new location and do a scan so Stash re-learns where the files are now located, the heatmap disappears from the scene card but is still present if you open the scene.

To get the heatmap back on the scene card, run a "Generate" task (it is sufficient to leave overwriting files off to speed up the process).

To Reproduce
Steps to reproduce the behavior:

1. Scan a video and matching funscript
2. Generate heatmap, note the heatmap is on the scene card.
3. On the file system, move the video and script to a new location.
4. Run a Scan so the video is re-discovered
5. Note the heatmap is now missing from the scene card, but shows under the playback window if you open the scene.

Expected behavior
Would expect the heatmap to not disappear if a video file is moved to another location.
Please note this is the -only- issue with moving files - previews etc work just fine. Only the heatmap-on-the-scene-card disappears. A Generate task will bring it back (sometimes needs a browser refresh after).
