Fix for Bug#3357 "If the statement is long, the error message is trunc and important info is lost";

in hard-coded replication messages, always put small-length info (error codes, explanation of the error) at the beginning,
so that it is not cut by truncation if the query is very long (which happens if the query goes first).
