Addition of vector of static vectors and its RealType static vector

This code does not compile. The compiler tries to use StaticExpressionTemplate, thus it fails.

    TNL::Containers::Vector<TNL::Containers::StaticVector<3,double>, TNL::Devices::Host, size_t> Tvec;
    Tvec.setSize(1);
    Tvec = TNL::Containers::StaticVector<3,double>{1,2,3};
    
    TNL::Containers::StaticVector<3,double>svec{5,6,7};
    Tvec = (2*Tvec) + svec;
