Enabling proper deep linking when creating controllers

Per #49 this *somewhat* worked in when running `yo kraken:controller path/to/my/code` but it broken on a few things. This corrects them, namely by resolving the path dynamically (https://github.com/paypal/generator-kraken/compare/deeplink?expand=1#diff-06ab2e25987c55ab1223758f0a1bb98aR63) rather than hard coding it.
