simfs_ph2 queue error

[sponchcafe]

The photophysics component produces a readerwriter-queue error indicating that one or more queues are note properly emptied, when the process terminates. Since the error only seems to appear when bleaching is enabled, this might be the set_state_if action handling the box-collision reset stream.

After the heartbeat update, ph2 does not jump to infinite time when terminating, to avoid indefinite heartbeats. Therfore pending collision events are not handled until the end of stream when bleaching is enabled.

The data output however should not be compromised by that.

Solution sketch

• explicitely empty pending streams before terminating
