require ../util/requireOptional not in right path

[ivanclaud]

HI

On file lib/transports/nodemailer/index.js required path for ./util/requireOptional seems to be incorrect. It should have been ../../util/requireOptional

Also one more issue on lib/util/requireOptional.js

Options packages require code seems to be incorrect
return require('pkg');

As per my knowledge it should have been
return require(pkg);

@ivanclaud just install Neagle's version instead of keystone-email:
npm i https://github.com/neagle/keystone-email.git#fix-nodemailer
