Avoid to append ./ automatically
Currently, due to ./ being appended automatically to any file, it's not possible to resolve node_modules for example.
Will solve https://github.com/TheLarkInn/angular2-template-loader/issues/31
Could break other projects which are not appending ./ for resolving local files.

This needs to be approached in a creative manner that still stands true to the intentional design of the loader.
eventually it should check whether the file exists in the current path, and if not resolve the node_modules... But it's error prone if 2 files / modules come with the same name.
