fix(test/lightwalletd): add an alternative log to the final integration test check

[teor2345]

Motivation

Sometimes lightwalletd goes straight to logging "Another refresh in progress", without logging "Mempool refresh error" first.

Review

This is a high-priority fix, but the test sometimes succeeds.

Reviewer Checklist

• Integration test passes

The Windows tracing conflict test might have failed due to PR #3755.

This has been timing out on a few PRs, i thought it was just happening on the Docker build, but in this PR it happened in all the tests (except macOS) test tracing_endpoint has been running for over 60 seconds. There's something odd with tracing_endpoint

This makes most test to hang indefinitely cc: @conradoplg

EDIT: Nevermind, I thought #3755 was merged
