MDEV-26247 MariaDB Server SEGV on INSERT .. SELECT

Browse Source 
This problem occured for statements like `INSERT INTO t1 SELECT 1`,
which do not have tables in the SELECT part. In such scenarios
SELECT_LEX::insert_tables was not properly set at `setup_tables()`,
and this led to either incorrect execution or a crash
