Chore: Refactor use require.resolve() for archetype discovery.

[ryan-roemer]

Use:

  try {
    // Require resolve it
    var modPath = require.resolve(name);
    pkgPath = path.join(modPath, "package.json");
    return require(pkgPath);
  } catch (err) {
    /*eslint-disable no-empty*/
  }

Which has problems identified by @exogen in #31 (comment)

Task:

• Fix the problems
• Re-add a similar snippet
• Move up the inference chain if possible.
