Michael Widenius 1d7b4c2689 MDEV-15738 Server crashes in my_strcasecmp_utf8 on query from I_S with UNION executed as PS ...

Problem was the Item_field::Item_field(THD*, Field*) had old code
that put a null pointer in orig_field_names. Now, when we have
proper re-prepare if table definition changes, this is not needed
anymore.
