Investigate recent CI issues

The level 29 emulator has been crashing before it can finish running tests pretty consistently over the last week (see the Actions tab), and it seems that some of the emulators have started timing out too. What's going on?

It would be super helpful to have access to the emulator's logcat to debug some of this stuff. There's no standard way to do this, and it seems to be tricky – @pyricau gave it a good try on another repo without success. But it must be possible, somehow.

Here's an example of a recent 29 failure (from #352):

com.squareup.workflow1.ui.tests.ViewTreeIntegrationTest > complex_modal_backstack_with_text_entry[test(AVD) - 10] FAILED 
Test failed to run to completion. Reason: 'Test run failed to complete. Expected 1 tests, received 0'. Check device logcat for details
Tests on test(AVD) - 10 failed: Test run failed to complete. Expected 1 tests, received 0. onError: commandError=false message=INSTRUMENTATION_ABORTED: System has crashed.
