GH#839: test: remove redundant unserialize() calls on get_post_meta() results (GH#839)

[superdav42]

Summary

Removed two remaining redundant unserialize() calls on get_post_meta() results in Site_Duplicator_Postmeta_Test.php. WordPress get_post_meta($id, $key, true) already applies maybe_unserialize() internally, so wrapping with unserialize() fails in PHP 8+ when the returned value is already an array. Commit dd3461d fixed one of three occurrences; this commit fixes the other two in verify_attachment_backfill() and verify_elementor_backfill().

Files Changed

tests/WP_Ultimo/Helpers/Site_Duplicator_Postmeta_Test.php

Runtime Testing

• Risk level: Low (agent prompts / infrastructure scripts)
• Verification: self-assessed: test-only change, removes double-unserialize on already-unserialized values; no logic change to production code

Resolves #839
