Commit author's name link is incorrect

[jfix]

I've just started using gren so maybe this is just bad usage on my part.

I've configured gren with the CLI (very nice 👍), and this is the config file:

---
  dataSource: "commits"
  prefix: ""
  includeMessages: "all"
  changelogFilename: "CHANGELOG.md"

I've generated the Changelog for an existing release via gren release --override. While this works well, I've noticed that each list item ends with the author name which is supposed to be clickable. I don't know why, but in my case, it uses my name, "Jakob Fix", instead of my id, @jfix. Therefore, because of the prefixed @ it makes the first name, @jakob, clickable, which is another Github user.

Here's an example from the CHANGELOG.md file which I also generated using gren changelog --override:

- [✨ Replace `electron-json-storage` with `electron-store` (dot notation!).](https://api.github.com/repos/jfix/pac-toolkit/git/commits/3a65f60133ea288e294266e69a26875af6ea4df6) - @Jakob Fix

I've added the configuration option username: "jfix" to the configuration file, hoping this would change things, but to no avail, unfortunately.

Here is the release: https://github.com/jfix/pac-toolkit/releases/tag/v1.1.0

Hey @jfix, thanks for your feedback.

This one can be easily tackled by changing what gets passed to the template.

github-release-notes/lib/src/Gren.js

Lines 429 to 436 in 78786b3

	_templateCommits({ sha, html_url, commit: { author: { name }, message } }) {
	return generate({
	sha,
	message: message.split('\n')[0],
	url: html_url,
	author: name
	}, this.options.template.commit);
	}

The information should come directly from author.login

//see https://developer.github.com/v3/repos/commits/#get-a-single-commit

"author": {
    "login": "octocat"

Just ran into the same thing and some other person showed up in my release notes... 💩 Has anyone taken this one on yet? In the meantime I manually fixed my release notes.

This is actually still a bug as the author we're looking for doesn't belong to commit.
