URL for embedded cartridges is empty (WATCHER ISSUE)

Embedded cartridges for OpenShift application have an URL property. Currently JBDS/JBT doesn't show any, all URLs are blank

Steps to reproduce:

1. ASSERT: make sure you have at least 1 application running
2. ASSERT: make sure you have at least 1 cartridge embedded to it, ex. mongo
3. EXEC: in OpenShift Explorer: select your embedded cartridge (ex. mongo) and pick Properties from the context menu
4. EXEC: in the properties view: check URL row.

Result:
It's blank, there's no URL shown. This happens to all embedded cartridges currently: mongo, mysql, jenkins, etc.

1. EXEC: pick Refresh from the context menu of the application (in OpenShift Explorer)
2. EXEC: switch to properties view and check URL again:

Result:
URL is still blank.
