Add traces to integration tests + suppress one flaky assertion. (#11595)

Fixes #11604

Most issues were caused by a problem with Project List flooding the network with its requests - this was fixed on develop.
But one assertion was flaky - it assumed we will see the "real" run result on `write` node, but sometimes it is immediately overwritten by dry run.

But the most important part of this PR is adding traces to Electron packages - it's should be much easier now to debug E2E test failures.

Also renamed the previously misnamed "E2E tests" to "[GUI] integration tests".
