InstantAppRegistry: adjust backwards compat cookie sig check.

InstantAppRegistry used to store cookies based on the hash of only
one of the signing certificates out of potentially multiple signing
certificates.  To prevent loss of stored cookie info for an app which
has multiple signing certificates, it needs to check if the stored hash
value corresponded to only one of those certs before this was corrected.
Since the order of signing certificates is not specified, all cert hashes
should be compared to see if one of them matches the stored value.
