SQL health check does not work

[kokosing]

Even that below query fails:

select nodes_count,
case nodes_count
when 9 then 1
else 1/0
end
from (
select count(*) nodes_count from system.runtime.nodes where state = 'active'
)

with:

com.facebook.presto.spi.PrestoException: / by zero

driver continues the work:
