Otherwise flaky tests will run then both, not a problem, but this is
just to trigger flaky check, since there is some tricky issue [1]:

So now you will get additional message:

Fix query cancelation in case of Distributed queries with LIMIT (when
the initator does not required to read all the data), since this cannot
be done until the query was sent (from the Query packet up to the empty
data Block), otherwise you will get:
