Don't upgrade to HD split if it is already supported

Browse Source 
It is unnecessary to upgrade to FEATURE_HD_SPLIT if this feature is
already supported by the wallet. Because upgrading to FEATURE_HD_SPLIT
actually requires upgrading to FEATURE_PRE_SPLIT_KEYPOOL, users would
accidentally be upgraded to FEATURE_PRE_SPLIT_KEYPOOL instead of nothing
being done.
