Subject: [PATCH] Bug 31087: Prevent stringification of null in return claims

The return claims table was stringifying 'null'. This patch updates the
code to check for definition so we don't stringify incorrectly

Note: This patch was split out from a follow-up on bug 28854 as we felt
it should be treated separately for backportability.
