MDEV-25080 Fix incorrect view names in printed queries

Browse Source 
When printing Item_direct_view_ref the printed field name must be
complemented with the view name/derived table alias.
For example, for "SELECT a FROM (SELECT a FROM t1) q" field `a`
in the select list must be printed as `q`.`a`.

But if the view was merged then the initial `q` does not make sense
any more so field `a` must be printed  as `t1`.`a`
