For shared events, marking them as "show on the homepage" doesn't work

[BradHN1]

Describe the bug
Reported by Debby Marion.
When a community admin shares an event to their community, it gets added to the list of "Events - My Community" (https://admin.massenergize.org/admin/read/events). If you click the star icon on that list it should add that event to your community home page. That doesn't work. As a workaround, you can go to the Home Page settings via the Pages tab on the community profile page, go to Events Selection, locate that event on the list and add it that way.

To Reproduce
Steps to reproduce the behavior:

1. Share an event
2. Find that event on Events My Community
3. Select the star to add to home page
4. Visit community site, and event is not there.

Expected behavior
Clicking the star icon should toggle the event on the home page.
