Azat Khuzhin 2efbeab5af tests: fix 00719_parallel_ddl_table flakiness in debug builds
In debug bulds each client invocation takes ~1 second, and on CI it can
take more if the node is under some load, so let's decrease number of
iterations.

Anyway CI runs each test ~1K times daily, and if there will be something
even this number of iterations should be enough.
