Live Photos: Sidecar video file dimensions are indexed incorrectly

[graciousgrey]

1. What is not working as documented?

On the files tab of the edit dialog a wrong video size is displayed.

2. How can we reproduce it?

Steps to reproduce the behavior:

1. Index a live photo, e.g. IMG_123.heic ("ImageSize": "4032x3024") + IMG_123.mov ("ImageSize": "1920x1440").
2. Go to the files tab of the edit dialog

For the .heic file, the correct size is displayed. For the .mov file, the size of the .heic file is displayed.

3. What behavior do you expect?

Display the correct size for all files.

With these changes, the correct file properties should be displayed after reindexing all affected files.
