KUDU-3613 fix flakiness in replace_tablet-itest
Before this patch, the ReplaceTabletITest.ReplaceTabletsWhileWriting
test scenario would fail in about 2% of runs, mostly in ASAN builds.
The issue was due to selecting the same tablet UUID by the
ReplaceRandomTablet() test fixture's function two times in a row
in case of scheduler anomalies when running on busy nodes.
