[Entity Analytics] Allow task status to be "claiming" in disable/enab…

…le test (elastic#196172)

## Summary

Closes elastic#196166

The test is checking that when we disable the risk engine, the risk
ewngine task is registered but not actively running.

This check originally checked if the task status was "idle".

We have had a failure where the task status is "claiming", reading the
docs about this task status (below) this is also an acceptable
"non-running" status

```
  // idle: Task Instance isn't being worked on
  // claiming: A Kibana instance has claimed ownership but hasn't started running
  //           the Task Instance yet
```

(cherry picked from commit 40bfd12)
