Info
The WiredTigerIndex class stores a copy of the collection name in a _collectionNamespace constant, but this becomes invalid on rename. Indeed the index should not refer back to its parent collection as that can change.

Only work remaining is adding a test case.

Removing the Collection* from the IndexDescriptor fixed this issue.
Steps to Reproduce
> db.x.insert({_id:1})
WriteResult({ "nInserted" : 1 })
> db.x.renameCollection("y")
{ "ok" : 1 }
> db.y.insert({_id:1})
WriteResult({
"nInserted" : 0,
"writeError" : {
"code" : 11000,
"errmsg" : "E11000 duplicate key error collection: test.x index: _id_ dup key: { _id: 1.0 }"
}
})
