Improve subscriptions logging

If the event is not sent to the destination it
was supposed to be sent to, it's hard to find
out why it was not sent, and what was the message
content the code was working with. Having additional
logging (mostly debug) helps with troubleshooting.

Tested:
Built an image with these changes, ran in QEMU,
enabled debug logging, setup subscription:
```
{
  "@odata.id": "/redfish/v1/EventService/Subscriptions/3489160873",
  "@odata.type": "#EventDestination.v1_14_1.EventDestination",
  "Context": "127.0.0.1",
  "DeliveryRetryPolicy": "RetryForever",
  "Destination": "http://127.0.0.1:8888/events",
  "EventFormatType": "Event",
  "HeartbeatIntervalMinutes": 10,
  "HttpHeaders": [],
  "Id": "3489160873",
  "MessageIds": [],
  "MetricReportDefinitions": [],
  "Name": "Event Destination 3489160873",
  "Protocol": "Redfish",
  "RegistryPrefixes": [],
  "ResourceTypes": [],
  "SendHeartbeat": false,
  "SubscriptionType": "RedfishEvent",
  "VerifyCertificate": true
}
```

and sent a message:
```
root@bmc:~# busctl call xyz.openbmc_project.Logging \
/xyz/openbmc_project/logging \
xyz.openbmc_project.Logging.Create \
Create 'ssa{ss}' \
OpenBMC.0.1.PowerButtonPressed \
xyz.openbmc_project.Logging.Entry.Level.Error 0

o "/xyz/openbmc_project/logging/entry/16"
```

Got this in the log:
