LU-4116 test: Correct error message search

replay-dual test_18 looks for "entering recovery in server" from
the local (client) console log. The problem is that this string
is split across multiple lines and the message should be searched
for on the MDS.

The error message to search for is changed to "not entering
recovery" and we are looking for it on the MDS.
