The outer iterator needs to move to the next segment when calling
__compose.
Without this change, `find_segment_if` would never reach the end of the
join_view which caused erroneous result when calling `ranges::find` on a
join_view of bidirectional ranges.
Other specializations using the segmented iterator trait were likely to
be affected as well.
