Constant deltachat::download::MIN_DELETE_SERVER_AFTER

pub(crate) const MIN_DELETE_SERVER_AFTER: i64 = _; // 172_800i64

If a message is downloaded only partially and delete_server_after is set to small timeouts (eg. “at once”), the user might have no chance to actually download that message. MIN_DELETE_SERVER_AFTER increases the timeout in this case.
