The test test_mv_merge_allowed asserts in two places that the tablet count is 2. It does so by calling an async function but, mistakenly, the returned coroutine was not awaited. The coroutine is, apparently, truthy so the assertions always passed. Fix the test to properly await the coroutines in the assertions. Fixes: SCYLLADB-905 Closes scylladb/scylladb#28875
