Fix count on a separate connection (fixes #18359)
Previosly count and other AR calculations would convert
column_name_for_operation to sql on a default Arel::Table.engine
(AR::Base) connection. That could lead to trouble if current
model has a connection to a different adapter or Base connection
is inaccessible.
