Logcat may be delivered with delay and that may result in missing logcat for last (n) tests (it's just a theory though)

I just wanted to point out, that [this](https://github.com/gojuno/composer/blob/2ff3f575152df48ee2659bbe746610dd633a04f7/composer/src/main/kotlin/com/gojuno/composer/TestRun.kt#L137) looks like something more than just a theory. AFAIR, we encountered missing or truncated logs during Composer evaluation almost year ago.
