CI test improvements

Some CI tests are unreliable. Current situation, from @shoriminimoe

I looked through the last 5 automated runs of the integration tests. Although there are a few flaky tests, I haven't found any showstoppers. For reference, these are the tests that failed along  with their failure rate.

Results are listed as "name: rate" e.g. "test: 1/5".
