Steps to Reproduce:

1. Create two instance of Liferay, one running on localhost:8080 the other on localhost:9080
2. Install these two patches on each server
3. Control Panel → Sites
4. Create first site, zebra
5. Create second site, zebra remote. Capture the site id.
6. Control Panel → Zebra → Site Settings. Enable Remote Live with localhost, local port 9080, zebra remote Site ID → Save.
7. Mobile Device Rules → Add Rule Group → Name="Tablet" → Save. This will create an MDRRuleGroup for the Site.
8. Site pages → Add page → "Home"
9. Site pages → Add page → "Two"
10. Site pages → Two → Mobile Rule Groups → Click "Define specific mobile rule groups"
11. Select Rule Group → Tablet. This will associate a custom MDRRuleGroupInstance with page Two.
12. Now delete page Two. Site Pages -> Two -> Delete
13. Now view the zebra site
14. Now try to publish the one remaining page to the Remote Live sites. Go to Home → Publish to Remote Live Now → Publish.

Intended Result: The page should publish successfully.
Actual Result: The publish fails (during the export step) with an error like this: com.liferay.portal.kernel.lar.PortletDataException: com.liferay.portal.NoSuchLayoutException: No Layout exists with the primary key 12914 (see attachment)
