I was checking that the scripted synthetic child provider's _python implementation_ is `None` with the [new API `SBValue::GetTypeSyntheticImplementation()`](https://lldb.llvm.org/use/variable.html#api-attached-synthetic-child-provider). That is to be expected if the SCP is implemented in C++, but for libstdc++ that is not the case, there is a Python implementation.

The now removed test wished to check if a `CXXSyntheticChildren` based SCP was compatible with `SBValue::SetTypeSynthetic()`s (another new API) ability to influence the SCP choice.
