MDEV-29199 Unique hash key is ignored upon INSERT ... SELECT into non-empty MyISAM table 

disable bulk insert optimization if long uniques are used, because they
need to read the table (index_read) after every inserted now. And bulk
insert optimization might disable indexes.

bulk insert is already disabled in other cases when there are chances
that the table will be read duing the bulk insert.
