Revert of Assert that only 0-numbered objects are Released() (patchset #7 id:120001 of https://codereview.chromium.org/2375343004/ )

Reason for revert:
Broke PDFExtensionTest when rolling DEPS in Chromium.

Original issue's description:
> Assert that only 0-numbered objects are Released()
>
> This condition holds because numbered objects are brute-force
> deleted by the indirect object holder, rather than being
> released.
>
> Be careful about recursive deletion, check before advancing,
> since we no longer count on Release() doing this for us.
> Fix a few tests where the test was violating ownership rules.
>
> This should be the last step before completely removing Release()
> in favor of direct delete everywhere.
>
> Committed: https://pdfium.googlesource.com/pdfium/+/aba528a362248a54b27a7e9e046e2b65ab83f624
