TString in ROOT support std::string_view which was added into C++17
standard and CMSSW since GCC 6 is compiled with C++17. GCC 7 will
provide a ful C++17 language support and most of C++ standard library.
TString defines two conversion operators, one for const char * and one
for std::string_view. The std::string can be constructor by both of them
thus causing compiler to error on it.
Use static_cast to explicitly select conversion operator which would be
compatible with previous C++ standards.
