Refactor for everywhere to use sendEmailFromTemplate everywhere

* Created a singleton to house handlebars so req doesn't need to be
  passed everywhere (should make unit testing easier later)
* Subjectline for sendgrid and nodemailer are both always prefixed in
  sendEmail()
* removed prefix subjectline from all other email places
* added a couple if (!event) { return 404 } to help make typescript
  happy
* some minor eslint auto fixes (looks like let => const where it can)
