changing a monthly recurring event to a date before will repeat events daily

## Prerequisites
- [X] I have searched open and closed issues for duplicates.

## Describe the bug
If there is a monthly recurring event, starting on the first of November for example, and you change the event so it starts the first of October, the events will be repeated daily between 1/10 and 1/11. This only happens in the backwards direction, not forwards.

### To Reproduce
Steps to reproduce the behavior:
1. Create an event of 1/11
2. Make it monthly recurring
3. Save
4. Edit event and change the start date to 1/10
5. Save

Daily events will now be added between 1/10 and 1/11.

### Expected behavior
Just one event should be created

### Screenshots or screen recordings

## Platform Information

- [ ] I'm using the latest version from git that I've manually compiled
- [X] I'm using the latest released stable version
