support aliases with serverless-bundle test

[ghost]

#104 Currently, aliases defined in the serverless.yml file are not taken into account when running 'serverless-bundle test'.

I mentionned two possible solutions.

I went for option 2 (as it was faster to add)

and added moduleNameMapper to the list of acceptedKeys in the createJestConfig.js file.

If this is something you are likely to consider, let me now and I will also update the README.md.

test

I didn't write any automated tests as it looks like npm run test-scripts has been removed from the .travis.yml file.

But I created a repo you can git clone to see serverless-bundle test run with aliases. (checkout the README.md)

PS

I also updated the README.md file to reflect the changes regarding "npm run test-scripts".

this will allow us to add our aliases to our package.json in a format jest understands (regex)

"jest": {
    "moduleNameMapper": {
      "libs(.*)$": "<rootDir>/libs/$1"
    }
  }

Thanks for this!

Yeah we changed the test command. It should be npm run test scripts instead of npm run test-scripts.

I added the test case and updated the docs. Merging.
