Hello world tutorial doesn't work

[leoloco]

Context
The hello world tutorial is supposed to be one of the entry point for future builders on the Massa ecosystem.
However the command specified in the tutorial to set up the project (followed by npm install) results in something that doesn't work.

Step to reproduce
Run
npx @massalabs/sc-project-initializer@buildnet init massa-hello-world
Then run
npm install
And finally
npm run test

Expected behavior => test pass
Current behavior => cannot find as-bignum

To fix
Update the command or update the sc-project-initializer so the user doesn't create non-functionning project
