🐛 Describe the bug

The tacker button is no longer being shown when accessing a github PR page

Expected behaviour

The button to start tracking time is shown and acting normally

Steps to reproduce

Steps to reproduce the behaviour:

1. Go to https://github.com/.../pull/<999>
2. See that the button is not there

Other details or context

In the console a message is shown:

TypeError: can't access property "textContent", titleElem is null
    <anonymous> moz-extension://9fc600f1-a537-4f87-be2e-a569c01daec8/src/content/github.js:1
    renderTo moz-extension://9fc600f1-a537-4f87-be2e-a569c01daec8/src/content/index.js:2289
 
Array []
index.js:12:63821

This is caused by the fact that

track-extension/src/content/github.js

Line 29 in cfeaca1

const titleElem = $('.js-issue-title')

does not find the .js-issue-title element and the error is raised in line 44 when it is referenced
