Accidental override when enabling <interfaces> for tables with columns X and IS_X in Kotlin

[lukaseder]

Kotlin's infinite wisdom placed in the cleverness of the isX:boolean property naming convention is a gift that keeps on giving, this time when enabling <interfaces> for tables with boolean columns X and IS_X:

CREATE TABLE t_11912 (
  x INT,
  is_x INT,
  is_y INT
);

Generated code produces this compilation error:

The workaround is to use a generator strategy, of course, or to turn off <interfaces>

I guess the @set:JvmName annotations on the subtypes should also be generated on the interface type?
