Describe the bug
When using the event list widget, the default/"baseline" date appears to be yesterday rather than today. This happens both when adding the widget and when clicking on the "today" button (the skeuomorph of a calendar with a small square in it at the top right corner).

To Reproduce
When adding the widget

1. Go to widgets>Fossify Calendar and add the event list widget.
2. Click "OK" on the config screen.
3. The widget loads events, with the start of yesterday being focused on by default.
   When clicking on the "today" button
4. Scroll down to a random point in time.
5. Click on the "today" button at the top right corner.
6. The widget scrolls all the way back to the start of yesterday.

Expected behavior
For both cases, the widget should default to today, with yesterday's event visible by scrolling up but out of view at the beginning.
Even preferably in my opinion, in both cases the widget should default to right now, i.e. with events that already happened today out of view. But that is a matter of opinion, and the start of today (with events today that already happened in view) is also acceptable.

Screenshots
This video demonstrates clicking the "today" button multiple times (each time the widget reloads happens after a click). When adding the widget you get to the same point as if you just clicked the "today" button.

Device info (please complete the following information):

• Model: Galaxy A12
• OS: Android 12
• App version 1.0.2 (early access)

Additional context
The main issue with this behaviour is you always have to scroll to see the closest upcoming events.

Hello @Aga-C, @apoumier and I are students at Paris 8 University and we have to chose a free software project to contribute to. We managed to reproduce this bug and we would like to resolve this issue. We will start working on it soon.

Hello, is it still possible to resolve this issue with @SunFlowerTos ? We would like to start working on it as part of our free software development course.

If there's no needs triage label, you can just work on an issue. You don't need to be assigned to it or have any permission to do it.

This could be optional. The default to be to suppress 'yesterday' from entering the list, with a toggle option to show yesterday when creating the widget. In this suggestion the toggle would be on the same screen as the "Show events happening within..." option, after initially placing the widget on your home screen.

Here is an example mockup I made in gimp.

@Gymcap There's already Display events from the past in settings where users can configure this for all event list widgets.
