Pulp

When a repo.publish.finish http event listener is triggered, the relevant repo publish task is still running

Version:
pulp-server-2.6.0-0.7.beta.fc21.noarch

How reproducible:
Always, automated

Steps to reproduce
- create an rpm repo with feed
- create an http event listener
- reporting to http://requestb.in/\`request_id\`
- update the event listener configuration types to: ['repo.publish.finish']
- publish the repo
- wait till repo publish tasks finish
- inspect the request bin

Actual results:
- the bin contains a request with a task call report in request.body such that task.state == 'running'

Expected results:
- the bin contains a request with a task call report in request.body such that task.state == 'finished'
