Normalize less decimal fields in System tests

Normalizing the `.1` and `.11` values were not needed see test result. The pass both on PDO and Mysqli. 

It is better to test for the full result including the `.11` and it is less confusing. For example I spent more than 1.5 hours this morning trying to figure out why a `*,11` was present when a German locale is used but an integer when an English locale is used.
