    Description

      When we CREATE indexes with defer build true, on a bucket with 1 scope and 100 collections and 0 documents , /stats API on one of thee indexer nodes returns this :

      "bucket-1:scope-1:collection-14:index14-2:num_docs_indexed": 0,
      "bucket-1:scope-1:collection-14:index14-2:num_docs_pending": 104448, 
      "bucket-1:scope-1:collection-14:index14-2:num_docs_processed": 0, 
      "bucket-1:scope-1:collection-14:index14-2:num_docs_queued": 0, 
      "bucket-1:scope-1:collection-14:index14-2:num_flush_queued": 0,
      

      which is also causing the UI to display - 104k mutations pending

      This should ideally be 0 mutations pending (as we never loaded the bucket with any documents since the beginning of the test)
