wallet: fix legacy spkm default birth time

Browse Source 
To avoid scanning blocks, as assumed by a wallet with no
generated keys or imported scripts, the default value for
the birth time needs to be set to the maximum int64_t value.

Once the first key is generated or the first script is imported,
the legacy SPKM will update the birth time automatically.
