debug tail 800 lines flake

Browse Source 
Sometimes this tests flakes but in the CI log I see all expected lines
printed but still for some reason the matcher fails.
Right now it will truncate the array so it is not possible to verify
what the matcher sees. Change this be removing the truncate limit for
this specific test only.

see #18501
