$collStats should check for presence of time series options rather than relying on namespace checks

      1. Create a collection "A".
      2. Create a collection "system.buckets.A".
      3. Run $collStats against "A" -> response will contain a bogus "timeseries" field, and stats will be reported for "system.buckets.A" rather than "A".

      It appears that when collecting collection statistics for a collection A, we check to see if system.buckets.A exists, and if so, assume that A is the view associated with time series collection system.buckets.A. However, it's possible to create a regular collection on such a namespace, and for this to prevent us from properly collecting stats on A.
