MDEV-24715 Assertion !node->table->skip_alter_undo in CREATE...REPLACE SELECT

Browse Source 
In commit 3cef4f8f0f (MDEV-515)
we inadvertently broke CREATE TABLE...REPLACE SELECT statements
by wrongly disabling row-level undo logging.

select_create::prepare(): Only invoke extra(HA_EXTRA_BEGIN_ALTER_COPY)
if no special treatment of duplicates is needed.
