Oran Agra 2b5f23197c stabilize tests that look for log lines (#7367)
tests were sensitive to additional log lines appearing in the log
causing the search to come empty handed.

instead of just looking for the n last log lines, capture the log lines
before performing the action, and then search from that offset.
