Core: VS tracers: don't complain about missing lb for non-virtual par…

[RudolfWeeber]

Fixes #2204

[fweik]

#include <boost/algorithm/cxx11/any_of.hpp>

[...]

if(boost::any_of(local_cells.particles(), [](Particle const& p) {
  return p.p.is_virtual;
}) {
      runtimeErrorMsg() << "Inertialess Tracers: No LB method was active but "
                           "virtual sites present.";
}

is almost a correct English sentence and does short circuit.
