[LU-12805] replay-single/36 is broken

Description

replay-single/36 seem to be very old, written at times of CFS when all tests were local:
if $LCTL dk | grep "stale lock .*cookie"; then
error "cancel after replay failed"
i.e. it checks for server-side messages on the client.
I noticed that having it failing constantly locally. then tried to change so that server side's lock is grepped: https://review.whamcloud.com/#/c/36127/ – all testing sessions failed in autotest.
AFAIU, ELC is the root cause - it packs cancels, then client doesn't replay cancelled locks but the original pack is sent anyway.
I think we should disable 36 at least.

hm, the test verifies that there should be no cancels after recovery, right? but they do come due to ELC.
