MAID-582_passing_DataManagerDatabase_tests

I agree in the "application code body", the log shall be reduced to minimum.
(However, I think the "removal" shall be just a comment out instead of taking out the code,
to ease a later on restoration for debugging.)
Meanwhile, I think those the logs in "testing code" shall be kept,
when the log give more description of the test (makes the test more readable)
and won't cause slow down in application code.
For example, the logs in this test case only happens during the stage of setup testing environment and comparing the result.
They gives more info of what has been setup and what result to be expected,
meanwhile has no affect on the performance of the target application code body.
