Fix class literals of objects in super constructor calls

In an expression such as "Obj::class" where Obj is an object, it's fine to
consider Obj either an expression or a type and generate either
Obj.INSTANCE.getClass() or Obj.class correspondingly. However,
the former fails in the object's super constructor call because the INSTANCE
field is not yet initialized. Thus, we force generation of Obj.class in case
when Obj is an object.

Note that this has been reproduced in our project, see
