fix(scala#19806): wrong tasty of scala module class reference

This commit makes the following diff to TASTy for i17255
files. The TASTy before this commit relied on the compiler (aka all TASTy clients)
intrinsically knowing how to resolve Module$ when the definition is actually Module[ModuleClass].

```sh
scalac tests/run/i17255/J.java tests/run/i17255/Module.scala -Yprint-tasty -Yjava-tasty
