User's events from Cloud Firestore for Firebase often aren't loaded

[danieldanielecki]

For some reason, usersEvents events from promiseUsersEvents sometimes aren't reflected on the Map. It might be combined with refreshingpromiseUsersEventsmore often than once a week. The external events can stay once a week, butusersEvents` should have been refreshed once a day, or have a button to refresh all the events.
