MDEV-15413 Unexpected errors upon CREATE TABLE .. WITH SYSTEM VERSIONING AS SELECT ...

Browse Source 
numerous fixes for CREATE ... SELECT with system versioning:
In CREATE ... SELECT the table is created based on the result set,
field properties do not count. That is
* field invisibility is *not* copied over
* AS ROW START/END is *not* copied over
* the history is *not* copied over
* system row_start/row_end fields can *not* be created from the SELECT part
