:table_name_with_underscore and set_table_name

When using :

config.active_record.primary_key_prefix_type = :table_name_with_underscore

and a model :

class SensorRecord < ActiveRecord::Base
  set_table_name 'data'
end

ActiveRecord will use the ModelName instead to table_name to build the IdName.
SQL Request done when querying SensonRecords :
SELECT COUNT(DISTINCT sensor_record_id) FROM data......

It should be "data_id" (table_name_with_underscore)
