The modified lines of code intend to await the first appearance of a log on one of the nodes. But due to misplaced parentheses, instead of creating a list of log-awaiting tasks with a list comprehension, they pass a generator expression to asyncio.create_task(). This is nonsense, and it fails immediately with a type error. But since they don't actually check the result of the await, the test just assumes that the search completed successfully. This was uncovered by an upgrade to Python 3.12, because its typing is stronger and asyncio.create_task() screams when it's passed a regular generator. This patch fixes the bad list comprehension, and also adds an error check on the completed awaitables (by calling `await` on them). Fixes #18740 Closes scylladb/scylladb#18754

If you can use an existing folder, consider adding your test to it. New folders should be used for new large categories/subsystems, or when the test environment is significantly different from some existing suite, e.g. you plan to start scylladb with different configuration, and you intend to add many tests and would like them to reuse an existing Scylla cluster (clusters can be reused for tests within the same folder).
To add a new folder, create a new directory, and then
copy & edit its suite.ini.
