1. Could not find a way to use TK_IgnoreUnlessSpelledInSource because code in function
`template <typename T>
void TemplatePositiveTest() {}`
is implicitly instantiated for different template types, so it is being ignored by matchers with TK_IgnoreUnlessSpelledInSource.
2. Renamed check to bugprone-smartptr-reset-ambiguous-call.
