Dedupe datatable incorrectly calculates rows

To replicate 

1) have more than 25 conflicted dedupe matches in the db (in this case 27)

2) go to dedupe find screen, select all and batch merge selected contacts.

3) observe that on the conflicts screen you can only access 25 (the rowCount) not all 27

This can be fixed at the jquery level by telling it the server is holding back information with the parameters
        "processing": true,
        "serverSide": true,
