iotests: 30: prepare to COR filter insertion by stream job

test_stream_parallel run parallel stream jobs, intersecting so that top
of one is base of another. It's OK now, but it would be a problem if
insert the filter, as one job will want to use another job's filter as
above_base node.

Correct thing to do is move to new interface: "bottom" argument instead
of base. This guarantees that jobs don't intersect by their actions.
