The fix for bug 46749 removed the check for OUTER_REF_TABLE_BIT 
and substituted it for a check on the presence of 
Item_ident::depended_from.
Removing it altogether was wrong : OUTER_REF_TABLE_BIT should 
still be checked in addition to depended_from (because it's not 
set in all cases and doesn't contradict to the check of depended_from).
Fixed by returning the old condition back as a compliment to the 
new one.
