The truncate method could be called from within a transaction. The flag
of GROUP_LOCAL was set in truncate method after statement row had been
being checked on the GROUP_LOCAL. Accordingly, after a local transaction
NOP row was not appended.

Closes #6123

The patch doesn't build on my machine. For the same reason as the other 
patch.
I suppose you'll fix that with the other patch.

Please, find a better test name.

Thanks  for the fixes!

One comment left. I'm pasting part of the patch here to review.

In test:

+g.after_each(function(cg)
+    cg.cluster.servers = nil
+    cg.cluster:drop()
+    fio.rmtree(cg.master.workdir)
+    fio.rmtree(cg.replica.workdir)
+end)
+
+
+g.before_test('test_truncate_is_local_transaction', function(cg)
+    cg.cluster:add_server(cg.master)
+    cg.cluster:add_server(cg.replica)
+    cg.cluster:start()
+end)
+
+g.after_test('test_truncate_is_local_transaction', function(cg)
+    cg.cluster:drop({cg.master, cg.replica})
+end)
+

You have a single test: test_truncate_is_local_transaction.

So g.after_each and g.after_test both have the same meaning in your case.

I propose to dorp g.after_test, since g.after_each supersedes it.

Also, you don't need to call fio.rmtree in g.after_each.
luatest does this for you, when needed.
