Asias He fd1c0e0bb3 streaming: Fix iterate and delete ...

The problem is that in start_streaming_files we iterate the _transfers
map, however in task.start() we can delete the task from _transfers:
stream_transfer_task::start() -> stream_transfer_task::complete ->
stream_session::task_completed -> _transfers.erase(completed_task.cf_id)

To fix, we advance the iterator before we start the task.
