VB. NET: multiple object initializers are not parsed correctly

Class Test
  Dim a, b, c, d As New Collection()
End Class

Expected: a, b, c and d all have a "Collection"-TypeReference and a
ObjectCreateExpression-initializer.
Actual: only d has a "Collection"-TypeReference and a
ObjectCreateExpression-initializer. a, b and c have a NullTypeReference
and no initializer.

After this bug is fixed, the VBNetOutputVisitor needs to be updated to
only output the TypeReference + Initializer for the last variable.
