NF: apply Ide suggestion to use Kotlin's toString

[Arthur-Milchior]

It was done by replacing (java.lang.)?T.toString(([^()])) by $1.toString()

then searching and correcting manually T.toString(

Then adding parenthesis manually when $1 was an expression (always a division)

There are build errors.

If you're going to do this, don't use regex, use the IDE
