The _createCollection() uassert mentioned in the description for SERVER-47123 was introduced in SERVER-37283.

Going by the comment above the assertion, we may be able to tell if the collection lock acquisition is requested by UUID or by namespace from the nsOrUUID argument.

For _createCollection(), we can probably convert to a combination of AutoGetDb and CollectionLock for now and defer the work on refining the assertion condition in AutoGetCollection.

Alternative, we could upgrade the lock mode (using this helper function) for system.views to MODE_X in _createCollection().
