Rename package in Eclipse plug-in tests. There was a mismatch of the package name of exported packages in the manifest and the actual package name. Eclipse complained about it. This must have somehow slipped through the cracks. In any case, this patch fixes this. Renames package com.redhat.thermostat.eclipse.model to com.redhat.thermostat.eclipse.test.model in the com.redhat.thermostat.eclipse.test plug-in.
