When performing a single-asset publication from the slave node to a master node, the publication doesn't work properly.

This issue occurs due to the way the changeSets are not cluster-aware, yet the export process is, so the master node cannot retrieve the required changeSet data

Steps to reproduce:

1. Setup a 2 node cluster
2. Create a site with local live staging enabled
3. From the master node, create a web content.
4. On the view web contents page, select the option icon next to the web content and select "Publish to Live".
5. Verify the web content is visible on the live site.
6. From the slave node, perform step 4 again.

Expected Results:

content is published to live.

Actual Results:

content is not published to live.
