Adding ownerId

We need to add our user id to the data we're about to sync to our App in the cloud. This way we'll be able to download it later if we need it.

So in MainView, when we create our list of Habits, we need to set the ownerId to the current log in user:

We 1st get our realm from the environment:

MainView.swift

    @Environment(\.realm) var realm

And then we use it to get the current log-in user id.

MainView.swift

    // ...
    if let habits = allHabitGroups.first {
            // ...
        } else {
            ProgressView()
                .onAppear {
                    let habits = Habits()
                    habits.ownerId = realm.syncSession?.parentUser()?.id ?? ""
                    $allHabitGroups.append(habits)
                }
        }
