RMLIOREGTC0004y, RMLIOREGTC0006y: booleans values from MySQL and SQLServer databases

[elsdvlee]

Test cases RMLIOREGTC0004y and RMLIOREGTC0006y expect expects booleans values as output but when uploading booleans values to MySQL and SQLServer databases these booleans are converted to intergers. Therefore, the values being generated are integers and not booleans.
