Enable to refresh ngdetails view

For now, refreshing ngdetails view by browser using F5 key or reload
button, it causes 404 error from django. To fix this issue, this patch
adds the url for '/ngdetails' into django.

To reproduce navigations, each request for views.py requires
'dashboard' and 'panel' object. Otherwise django side returns
500 error.

However the URL for request of details page (i.e. /ngdetails/)
can not provide informations to set the proper navigation.

So this patch set them to default dashboard and default panel.

This patch focuses to prevent 500 error. So the issue for
settings of proper navigation will be fixed by subsequent patch.
