Perhaps, still I'm not completely sure if this assumption is going to
always stand for all the possible configurations we support.  So,
rather than coming back to this test again, I would choose to make the
test as stable as possible from the start.  That's what mapping with
the error message would offer when grabbing the LSN from the CONTEXT
part of it, because there's a one-one mapping between the expected
ERROR and its CONTEXT from which the information used by the test is
retrieved.
