Function place_for 

pub fn place_for(
    chosen: &str,
    list_account: &str,
    calendars: &[Collection],
    makes: bool,
) -> Place

Where a task’s blocks go: the calendar chosen in Tasks ⚙ (chosen, “account/id”) while it can be written and takes events; else the one made for them on the account of the task’s list (list_account), or on this device when that list is kept here or its account makes no calendar from Sioul (makes: Google’s makes none).
