Include model.spec.js for endpoints

[drochag]

The user model on the initial app includes user.model.spec.js. It would be nice that the generator automatically includes that because it's not on the list of created files

$ yo angular-fullstack:endpoint client
? What will the url of your endpoint be? /api/clients
   create server/api/client/index.js
   create server/api/client/index.spec.js
   create server/api/client/client.controller.js
   create server/api/client/client.events.js
   create server/api/client/client.integration.js
   create server/api/client/client.model.js
   create server/api/client/client.socket.js
