Tests in epoxy-integrationtest are flaky

[pmecho]

While working on a PR I had a failure running ./gradlew check. I thought this might be related to my bumping of androidx.test:core to 1.3 but I also get the same flakiness on 1.2. One example is that they were successful 3 times in a row and the 4th time is when they failed.

One stacktrace is:

Thanks for reporting, I saw this too, but thought I fixed it :( I think it started after bumping some dependency, potentially robolectric to 4.4

i'm not going to prioritize for now as it passes most of the time, but need to get to it at some point.

fixed in #1055
