Running npm command 'test' should not fail on windows OS

[HNeukermans]

When running npm 'test' command on windows OS, i get an error saying
'Rm is not recognized as an internal or external command'.
Installing npm package rimraf globally and then changing 'rm' to 'rimraf', did the trick.

Hi!
You can use the git bash to execute "npm start".
It should not throw an error on "rm".
