title: Wrong DEFAULT_SERVICE_PATH variable
body: <p>When importing data model from external service which in this case is an xsodata source, I see that the VDM creates a wrong DEFAULT_SERVICE_PATH. Indeed the original service contains a "." inside like this "/xsodata/Internals.xsodata/$metadata",

  but when checking the service generated by the VDM when importing data from external service in SAP Web IDE, I see this:
  String DEFAULT_SERVICE_PATH = "/xsodata/Internalsxsodata";
  without the "."

  I had to add the "." manually.</p>
  
  <p>Could you please check?</p>
