BUG#42742: crash in setup_sj_materialization, Copy_field::set
- If a semi-join strategy covers certain [first_table; last_table]
range in join order, do reset the sj_strategy member for all tables
within the range, except the first one.
Failure to do so caused EXPLAIN/execution code to try applying two
strategies at once which would cause all kinds of undesired effects.
