Remove TString where possible and use specific conversion functions

[davidlt]

This is because we are in C++17 and TString support both conversions, std::string and std::string_view and so does C++ Standard Library (e.g., std::string ctors and operators) thus compiler doesn't know what to do.

This pull request is fully signed and it will be integrated in one of the next CMSSW_9_0_X IBs (tests are also fine). This pull request requires discussion in the ORP meeting before it's merged. @davidlange6, @smuzaffar
