[Bug Report] Excluded Tags does not apply to Identify tasks

[bayured]

Describe the bug
The Excluded Tags list is ignored when using an Identify task. The feature works as expected when scraping individually.

To Reproduce
Steps to reproduce the behavior:

1. Go to Settings and then Metadata Providers.
2. Add some tags into Excluded Tag Patterns.
3. Run an Identify task on a scene with excluded tag(s) present on scraped side.
4. View the scene. Tag(s) in the Excluded Tags list have been scraped.

Expected behavior
Either excluded tags should document they do not apply to identify tasks or the feature should apply across all methods of scraping.

Stash Version: (from Settings -> About):
v0.27.2-37-g0621d871

Additional context
I think this broke in #2391 but haven't tested. I re-added the removed code in postProcessTags in pkg/scraper/postprocessing.go and it resolved the issue but I presume there's a cleaner way to fix but I don't understand how the identify flow works.
