Build Analysis: Empty "Assets" window for scripts-only builds

Steps to reproduce:

1. Create a project
2. File -> Build Profiles -> Add Build Profile
3. Select the macOS platform and click the "Create Build Platform" button
4. Create a build
5. Window -> Analysis -> Build Analysis
6. Verify that the build data is displayed in the "Assets" tab
7. Click the kebab menu and select "Delete All Builds..."
8. Return to the Build Profiles window and create one more build
9. Return to the "Build Analysis" window
10. Observe the "Assets" tab 

Actual results: The build analysis tracking data is completely missing or blank. The build overview lists 0 Assets. The Assets tab grid contains no rows, and the broken footer text reads "Showing 0/0".

Expected results: The newly completed build report should accurately parse and display the project's build details, total asset size, build step durations, and the populated table listing all compiled assets

Reproducible with versions: 6000.6.0a5, 6000.6.0a6

Can’t test with versions: 6000.6.0a5 has no needed new functionality
