07e0cab4 - When trying to restore a keyback that has its key in 4S, check if 4S will be readable

When trying to restore a keyback that has its key in 4S, check if 4S will be readable If the account data for the 4S key is cleared or lost somehow, don't attempt to read the key and ask for the passphrase/recovery key instead, as doing so would trigger another bootstrap from the restore key backup dialog, overwriting the existing key backup.
