  -----------
  [Clang][Sema] fix assertion failure about invalid conversion when calling lambda (#96431)

fixes https://github.com/llvm/llvm-project/issues/96205

The cause is that some `Conversions[ConvIdx]` here is not initialized 


https://github.com/llvm/llvm-project/blob/eb76bc38ffc286e62fdb8f8d897b5de04b2575be/clang/lib/Sema/SemaOverload.cpp#L7888-L7901

and we do not check whether `Cand->Conversions[I]` is initialized or not
here.
