Trim issue titles

[martincostello]

Somehow I managed to create a series of issues last month (I assume some weird copy-paste thing) that contained \r at the end of their titles. For example, this pull request, of which here's a snippet:

{
  "url": "https://api.github.com/repos/martincostello/update-static-assets/pulls/282",
  "id": 1454674049,
  "node_id": "PR_kwDOHxs9d85WtJCB",
  "html_url": "https://github.com/martincostello/update-static-assets/pull/282",
  "number": 282,
  "state": "closed",
  "title": "Add actionlint\r", // <-- No idea how I managed to do this!
  "user": {
    "login": "martincostello"
  }
}

This then causes the Markdown table rendering to break (example, notice the PR links starting to appear in the first column).

This pull request fixes that by trimming the issue title before rendering.

It also fixes a test assertion that is failing on my computer even without these changes. As I'm based in London, I assume that makes me equal to UTC here (even though we're currently in Daylight Savings at GMT+1)?
