Vicențiu Ciorbaru a1e589be9b MDEV-13354: Server crashes in find_field_in_tables upon PS with window function and subquery ...

When creating an Item_direct_view_ref we were setting the
Name_resolution_context based on TABLE_LIST::view member variable.
However, for derived tables this member is NULL. To not set a wrong
context, if TABLE_LIST::view is empty, use THD::lex instead.
