config_toolset.bat ingores toolset from bootstrap.bat and used the latest installed Visual Studio

Issue: When specifying a toolset in bootstrap.bat, still the latest Visual Studio is used - at least to compile b2.
This is because config_toolset.bat calles vswhere_usability_wrapper.cmd w/o parameters and vswhere_usability_wrapper.cmd returns the highest installed version first.

Simple patch - just to show the workflow
