Added status message for initiating Copy Page Hierarchy and Long Task APIs

Hi @Andrew.Ngo and @SimonKliewer

I’m still seeing this structure in the response to the fetching long task API:

{
  "id":"2160164865",
  "name":{"key":"com.atlassian.confluence.api.impl.service.longtasks.BulkPageCopyTaskRunner","args":[]},
  "elapsedTime":3570,
  "percentageComplete":100,
  "successful":true,
  "finished":true,
  "messages":[{
    "translation":"{\"status\":{\"key\":\"STATUS_COPIED_PAGES\",\"translation\":null,\"args\":[\"4\"]},\"destinationUrl\":\"/spaces/A21/pages/2160001036/Home+page\",\"totalPageNeedToCopy\":4,\"errors\":[]}",
    "args":[]
  }],
  "_links":{"base":"https://jdbevan.atlassian.net/wiki","context":"/wiki"}
}

instead of the fields documented on the docs page or on this CDAC post Add additional fields to “Get long-running task” & “Get long-running tasks” REST API endpoint response objects from a year ago…

Can you provide any insight?
