Fix EXPLAIN ANALYZE SELECT INTO not to choose a parallel plan.

We don't support any parallel write operations at present, so choosing
a parallel plan causes us to error out.  Also, add a new regression
test that uses EXPLAIN ANALYZE SELECT INTO; if we'd had this previously,
force_parallel_mode testing would have caught this issue.
