Make single_node_truncate.sql re-runnable

First of all, this commit sets next_shard_id for
single_node_truncate.sql because shard ids in the test output were
changing whenever we modify a prior test file.

Then the flaky test detector started complaining about
single_node_truncate.sql. We fix that by specifying the correct
test dependency for it in run_test.py.
