Improve GET/Count based on base table view instead with translation

[norbertbede]

example
when i run get query against table fv_m_product the rest api start a count operation. but i would say absolutely unnecessary do thos over _vt table (if table has translations)

produced SQL

SELECT COUNT(*)
FROM fv_m_product_VT
WHERE  AD_Language = $2)
AND   IsActive = $3 
AND   fv_m_product_VT.AD_Client_ID IN ($4,$5)

example
100k products witht 5 languages = 500k records, whoch costs much more then count over 100k

proposal
improve rest count on translation tables isview='Y' use base table for count instead translated view in database }_vt)
