The fix to 6990008, removed the COnfig.getProps call, which was implemented wrong.
However, the remaining non-test use case, listing all properties in the colsole, is not correct implemented as Props.get().
This gets the properties without the variables expanded.
after enumerating the property keys it needs to call back to
Config.getStringProperty(key) to get the values instead of directly calling p.getProperty(key)

Also, all the config properties are set as system properties, but now they are set in their pre-expanded form. They need to be set in the expanded form.
