When a PR/issue title contains backticks the contents inside the backticks should not be escaped when generating markdown. For example, in *this* project https://github.com/github-changelog-generator/github-changelog-generator/pull/566 results in incorrect markdown in the [generated changelog](https://github.com/github-changelog-generator/github-changelog-generator/blame/595ba5a8ae5c0f53ac25fb0136d594f68d945e6f/CHANGELOG.md#L140).
