Changed Query for validation statistics to add refMatch field

[peppermint-juli]

Datasets query clean up—added Ref match field to query as well.

probably need to change along the line I suggest based on Tina's comment.

from Tina's response, that the refmatch should count unique publications, i gather that the following should be the query:
declare @run_id bigint = ${run_id}
declare @refmatch_id bigint
select @refmatch_id=id from model where name='refmatch'
;
with valid_datasets as (
SELECT da.parent_alias_id
FROM snippet_validation sv
join dyad d on d.id=sv.dyad_id
JOIN dataset_alias da ON d.dataset_alias_id = da.id
where sv.run_id = @run_id and sv.agency_dataset_identified = 1
union
SELECT da.parent_alias_id
FROM dyad_model dm
join dyad d on d.id=dm.dyad_id
JOIN dataset_alias da ON d.dataset_alias_id = da.id and d.run_id = @run_id
where dm.model_id=@refmatch_id
)
SELECT 'n_datasets' k, count(distinct parent_alias_id) v FROM valid_datasets
UNION
SELECT 'n_refmatch' k, count(distinct d.publication_id) v
FROM dyad_model dm join dyad d on d.id = dm.dyad_id
WHERE dm.model_id=@refmatch_id and dm.run_id=@run_id
