Patryk Jędrzejczak 7caacf958b test: test_zero_token_nodes_multidc: properly handle reads with CL=ONE 
The test could fail with RF={DC1: 2, DC2: 0} and CL=ONE when:
- both writes succeeded with the same replica responding first,
- one of the following reads succeeded with the other replica
  responding before it applied mutations from any of the writes.

We fix the test by not expecting reads with CL=ONE to return a row.

We also harden the test by inserting different rows for every pair
(CL, coordinator), where one of the two coordinators is a normal
node from DC1, and the other one is a zero-token node from DC2.
This change makes sure that, for example, every write really
inserts a row.

Fixes scylladb/scylladb#22967

The fix addresses CI flakiness and only changes the test, so it
should be backported.

Closes scylladb/scylladb#23518

(cherry picked from commit 21edec1ace)

Closes scylladb/scylladb#24985
