Fix a regression on test galera_sr.GCF-572 introduced by commit
c9a6adba. This commit partially reverted a trivial test fix for
the galera_sr.GCF-572 test (commit 11ef59fb), which was targeted
at 10.6.
This is backporting the fix from commit 11ef59fb fix to 10.5, so
that the test stays the same all versions >= 10.5.

This patch changes statement rollback for streaming replication.
Previously, a statement rollback was turned into full transaction
rollback in the case where the transaction had already replicated a
fragment. This was introduced in the initial implementation of
streaming replication due to the fact that we do not have a mechanism
to perform a statement rollback on the applying side.
This policy is however overly pessimistic, causing full rollbacks even
in cases where a local statement rollback, would not require a
statement rollback on the applying side. This happens to be case when
the statement itself has not replicated any fragments.
So the patch changes the condition that determines if a statement
rollback should be turned into a full rollback accordingly.
