FluidSystem::getMainComponent returns the main componet index of the phase.
This doesn't actually make sense for the tracer models which why this commit also
* removes getMainComponent for tracer fluid systems (Changelog amended)
* guards all occurences of getMainComponent in code that works for tracer too
with constexpr if

The idea of the tracer model is really tied to Fickian diffusion and components
with small concentration diffusing in a bulk phase. Hence also it's name.
The Maxwell-Stefan test actual models 3 gaseous components where none of
the components is really the main phase but most importantly there is no
bulk phase with a main component that is not considered in the equations.
Thus the 1pnc model is the right choice for such a test.
This changes the test to derive from the 1pnc model. As for the given
setting with only Neumann boundaries the 1pnc wouldn't convergence for
a compressible fluid, the Ideal gas law is used to model a
compressible gas.

The same test actually exists for the 1pnc model already in 1pnc/implicit/1p3c.
Thus this commit simply removes the tracer test.

With the reduced number of arguments to be passed to the lambdas that
return the considered tensor (permeability / diffusion coefficient /
thermal conductivity), we don't need this interface anymore that was
mainly designed to obtain all the arguments that were required for the
tensor lambda interface.

Since we store the effective coefficients in the volume variables we
don't need the cumbersome extraction of permeabilities, diffusion
coefficients etc. anymore.
