Oleksandr Byelkin c2c93fc6e4 MDEV-14164: Unknown column error when adding aggregate to function in oracle style procedure FOR loop 
Make differentiation between pullout for merge and pulout of outer field during exists2in transformation.
In last case the field was outer and so we can safely start from name resolution context of the SELECT where it was pulled.
Old behavior lead to inconsistence between list of tables and outer name resolution context (which skips one SELECT for merge purposes) which creates problem vor name resolution.
