Datagrid sorting updated to match plot sorting

Looks like there is a navigation bug when clicking on data grid cells. I think originally the returned cursor would grab the first column, which would be observation_unit_id, now it looks like it grabs another column, which leads Collect activity to the wrong plot.

This probably needs to be updated to reference the column of the unique id:

//unique name column is always the first column

val uniqueIndex = cursor.getColumnIndex(cursor.getColumnName(0))

Thanks Chaney. I also noticed the trait navigation wasn't working like it used to, I think because of the recent addition of the LAST_USED_TRAIT preference. let me know if the fix here looks alright.
