Fix erasure of Thistypes.

Thistypes erased to the underlying class. This is wrong. When seen as part of some other type,
a ThisType has to erase to the erasure of the underlying type (i.e. the erasure if the selftype
of the class). unittest-collections.scala failed with a MethodNotFound error because the erasure
was computed incorrectly.

On the other hand, a tree with a ThisType type, should keep the type, analogous to a
tree with a TermRef type.
