This seems because we are very aggressive reporting error while running about:login testcases, as long as [the error is not in the white list](https://searchfox.org/mozilla-central/rev/f62d42b1d98e67dc3da05d586f71103df02b8c4a/browser/components/aboutlogins/tests/browser/head.js#100-153).

Since in the failed try task, the `"NotFoundError: No such JSWindowActor 'MarionetteEvents'"` errors occurs every time we run a new test manifest, I don't this is something caused by the password manager code. Bug 1710079 also has the same issue (The difference is that in Bug 1710079, the error doesn't occur in every manifest run).

I'm not sure if the error is something we want to fix, or it is just a "normal" error that might occur while running these testcases, but I can provide a patch that filter out those errors while running about:login tests so we behave just like the other testcases (don't care the error).
