Datasets counts are inflated

[afgane]

The gxadmin dataset-count command used in the script includes deleted datasets:

$ gxadmin query dataset-count 2007-01-01
 num_datasets
--------------
         6742

$ gxadmin query q "SELECT count(id) FROM dataset where create_time<'2007-01-01'"
 count
-------
  6742

$ gxadmin query q "SELECT count(id) FROM dataset where create_time<'2007-01-01' and deleted=false"
 count
-------
  1090

We likely don't want those counted?
