fix(PositionBuilder): Position of annotations on type reference are included in parent position

[nharrand]

fix #3321

Reproduces #3358

[nharrand]

This a cleaner workaround for #3359 . It fix the position of annotated CtTypeReferences.

Yet it still does not handle the case AnnoUser#m6() where a mix of annotation affect alternatively the type reference and the variable in an unfortunate order.
But the approach here cannot handle this case. To do it perfectly we need a post processing pass on all annotations and their parent to update parents positions.
