Collection list is displayed for every resource page. Bug Fixed

Previously collection list was not displayed due to some conflicts in displaying according to publish policy of evey resource. Previously for every resource page after publish the node object was getting retrieved from rcs, in which ObjectId's are stored in different patterns ,hence it was not been able to display the collection list except for the first time.

Modification in : 
```
node_edit_base.html  -->  little modification in loop
page.py  -->  Given a condition according to node status is 'PUBLISHED' or 'DRAFT'
```
