Console errors from Trello OAuth

[HarshdipD]

Describe the bug
Not necessarily a bug, but I did not spend a lot of time working on the Trello OAuth. It works perfectly, but following different tutorials, I might have added code that's not needed, which shows me errors.

To Reproduce
Steps to reproduce the behavior:

1. When using the extension for the first time, it directs you to the settings page, where you authorize Trello.
2. After this step, errors can be seen in the console.

Expected behavior
No errors on the console

Screenshots

Additional context
This does not give any actual errors to the user, but I'd like to see these errors from console gone. If you're interested in solving this, please comment on this thread. Please make sure to describe your process in solving this issue in the pull request so we can learn too!

Also, the last 2 errors in the screenshot above were introduced by #23, it should be easy to fix so no need for a new issue.

Update: sendResponse error has been removed by simply removing the function from popup.js, I don't think that breaks anything. Only 1 error is left.
