> With ref. to GROOVY-8880, it seems Instance Init Blocks in Traits are appended/called
only when there are fields defined in the same trait. 
> Example:
> {code}
> trait TraitOne {
>     {
>         System.out.println("Does not work")
>     }
> }
> trait TraitTwo {
>     Integer instanceCounter //immutable, non-shareable
>     {
>         System.out.println("Works")
>         instanceCounter = 1
>     }
> }
> class ClassWithTrait implements TraitOne, TraitTwo {
> }
> new ClassWithTrait().instanceCounter
> {code}
> Output:
> {code}
> Works
> {code}
> Expected output (order may differ):
> {code}
> Works
> Does not work
> {code}
