Fix wrong error code in the test case.

The replication slave sets first error 1913 and immediately after error
1595. Thus it is possible, but unlikely, to get 1913. The original test
seems to realise this, but uses an invalid error code - my guess is
that this was a temporary code used in a feature tree, which was then
forgotten to be fixed when merged to main. The removed "1923" is
something committed by mistake during tests.
