fix: Set awesome-typescript-loader version to 2.2.1

[JSMike]

The most recent update to awesome-typescript-loader is breaking new builds, hard coding the version to 2.2.1 resolves the issue for now

Fixes issue #1997

[JSMike]

The initial angular-cli@webpack version was using "awesome-typescript-loader": "^2.1.1" so this could potentially impact all angular-cli@webpack versions when creating a new project or when updating dependencies.

Why does 2.2.3 cause errors? 😏 Find out why and then update the PR accordingly to make it work and I'll accept PR :)

#1993 Already fixed as of right now. Thank you!

[JSMike]

@TheLarkInn Thank you, was just in response to #1997. If #1993 fixes it then we're good to go.
