[Passpoint] Fix connected network not showing in Wi-Fi picker

Newly added network by OSU does not appear in Wi-Fi picker even
when connected.
Root cause: newly added unique identifier included the certs and
key material in the hash, but after the profile is installed,
the certs and keys are moved to keystore and removed from the
configuration, hence the change in hash.
