Selective testing for include-neutronics = true/false

[billingsley-john]

include_neutronics=true/false has been left out of the selective testing matrix because some scripts still have neutronics dependencies which cause their tests to fail in the non-neutronics tests. I.e. the run_scripts.sh bash script can run specific tests depending on the value of include_neutronics. When = false, a docker image is built without neutronics dependencies so should only run tests that don't have neutronics in them. However, some scripts still have neutronics dependencies which cause failures.
