Fix //:module_test Conversion_MultiCUDA (#79926)
Fixes #79871
Make `module.cpp` tests respect change that was made in #78436 (no int types in autograd).
Note that there still a gap in Cmake test -- it's unclear why it didn't fail CI before.
As far as I can tell it should be executed, because it's included here https://github.com/pytorch/pytorch/blob/79507d2a9d06d4a3fb50eb21b30e08cc044776ce/test/cpp/api/CMakeLists.txt#L17:L17
