Description

DocumentNodeStore should provide same NodeState for given (path, revision) whenever a NodeState is obtained from it. This fails in some cases if the Node cache in DocumentNodeStore gets overflown and then the NodeState returned differs. This causes issues like

1. Spurious Commits see - Some commit would fails with conflicts in paths which were not modified in that commit
2. Diff logic would traverse those paths which are not related to changes done in that commit

More details would be provided in comments below
