Disable @typescript-eslint/no-this-alias rule

[achingbrain]

This rule stops you from doing things like:

const self = this

function foo () {
  return self.derp()
}

It prefers:

const foo = () => {
  return this.derp()
}

Which is fine. The problem is fat-arrows can't be generator functions and we use them all over the place so you have to use this aliases:

const self = this

function * foo () {
  yield self.derp()
}
