jasmine --helper flag broken following addHelperFiles() removal

[lucaswerkmeister]

$ npx jasmine --helper=. .
/home/luwe/.npm/_npx/b5e471128a280083/node_modules/jasmine/lib/command.js:143
    jasmine.addHelperFiles(env.helpers);
            ^

TypeError: jasmine.addHelperFiles is not a function
    at runJasmine (/home/luwe/.npm/_npx/b5e471128a280083/node_modules/jasmine/lib/command.js:143:13)

28f9495 removed addHelperFiles(), but runJasmine() in command.js still calls it.
