Fix coredump during subscription

Commit 4b712a29debc1a0860cc04850b262203cad402a5 [1] a bug on missing the
subscription copy from user persistent data when subscription object is
created, and it may cause a bmcweb crash.

Tested:

- Create subscription (e.g. Redfish Event Listener)

-  Create a dump
```
curl -k  -X POST "https://${bmc}/redfish/v1/Managers/bmc/LogServices/Dump/Actions/LogService.CollectDiagnosticData" \
 -H "Content-Type: application/json" -d '{"DiagnosticDataType": "Manager"}'

curl: (56) OpenSSL SSL_read: SSL_ERROR_SYSCALL, errno 0
```

BMC journal will contain like
```
