The loader is writing to pending replica even when write selector is set to previous. If migration is reverted, then the writes won't be rolled back as it assumes pending replicas weren't written to yet. That can cause data resurrection if tablet is later migrated back into the same replica. NOTE: write selector is handled correctly when set to next, because get_natural_endpoints() will return the next replica set, and none of the replicas will be considered leaving. And of course, selector set to both is also handled correctly. Fixes #17892. Signed-off-by: Raphael S. Carvalho <raphaelsc@scylladb.com> Closes scylladb/scylladb#17902

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.
