Fixes #1198. The summary used to show negative numbers when entries were added. There was also no option to show the added entries.

Hi there, thanks for this contribution! I'd love to see some tests with this, though I recognize that haven't written any tests for this in the past.

We have two methods for testing this that could be fine - the normal pytest unit tests in tests/unit, or the pytest-bdd tests in tests/bdd. You're welcome to take either approach.

And if you're not interested in adding that in, that's absolutely okay. Just please let us know so we can take that on.

Hi. Thanks for the welcoming response. Unfortunately, I'm not familiar with testing in python. I would love to learn. Please feel free to add anything to the pull request. I will take a look at the changes and use them as an example for future contributions.

Added tests

[micahellison]

OK, I added in some BDD (Gherkin) tests, though I excluded DayOne since it has its own way of dealing with this issue, which I think is beyond the scope of the PR.

I also ran into some cache issues (hence the failing tests in GitHub actions) but resolved them in #1373.
