MCOL-2178 Fix for handlers fallback mechanism patch.

Browse Source 
I returned if predicate that guards FE-BE initial connection
block. This predicated had been removed by accident in cb36041

Since we switched to internal ORDER BY FE now reduces the
default limit value to uint64-2 this broke a predicate check
for correlated subqueries. I replaced a predicate with more
reasonable to avoid false positives.
