element: fix posting of async-start messages

When an element lost its state but was busy doing a state change, still post the
async-start message with the base_time reset flag or else we might end up with
an old base_time.

this can happen when a sink is goin async to paused and then a flushing seek is
performed. This would cause the base_time to remain unmodified because the
async-start message was not sent.
