fix: preserve exporter incomplete objects

[superdav42]

Summary

• Preserve __PHP_Incomplete_Class values in the site exporter database search/replace path before object property mutation.
• Add a regression covering serialized payloads that contain an incomplete object plus replaceable URL data.

Verification

• php -l inc/site-exporter/database/class-replace.php
• php -l tests/WP_Ultimo/Site_Exporter_Test.php
• vendor/bin/phpcs inc/site-exporter/database/class-replace.php tests/WP_Ultimo/Site_Exporter_Test.php
• git diff --check
• Standalone exporter probe: warnings=0 old=yes new=yes

Not Run

• vendor/bin/phpunit --filter test_recursive_unserialize_replace_preserves_incomplete_objects is blocked locally because /tmp/wordpress-tests-lib/includes/functions.php is missing.

📝 Walkthrough

Walkthrough

This PR adds a guard clause to Replace::recursive_unserialize_replace() that detects and returns \__PHP_Incomplete_Class instances unchanged, preventing further recursion. A regression test verifies the behavior generates no warnings and preserves both old and replaced URLs in the serialized output.

Changes

Incomplete object handling

Layer / File(s)	Summary
Incomplete object guard and regression test inc/site-exporter/database/class-replace.php, tests/WP_Ultimo/Site_Exporter_Test.php	recursive_unserialize_replace() checks for __PHP_Incomplete_Class and returns it unchanged to prevent warnings. Regression test constructs an incomplete serialized object, installs an error handler, invokes the method via reflection, and asserts zero warnings plus both old and replaced URLs in the result.

Possibly related PRs

• Ultimate-Multisite/ultimate-multisite#1419: Both PRs add explicit handling to detect __PHP_Incomplete_Class during unserialize/recursive URL replacement and return/preserve those incomplete objects unchanged (in recursive_unserialize_replace() vs MUCD_Data::try_replace()), so the logic and regression coverage are directly aligned.

Poem

A rabbit hops through serialize deep,
And finds odd objects incomplete to keep—
No warnings now, just pass them by,
With URLs replaced, the site won't cry! 🐇✨
