Fix emulator tests.

[copybara-service]

Fix emulator tests.

I see success, at least in the one time I tried after my final fix: 23, 26, 30.

Those each took around 15 minutes or more, so that's probably slower than the ~13m on the Hilt job. So it presumably makes sense to keep the emulator tests running only after merges to master, rather than running them on pull requests, even if we charitably assume that my fix will keep them working reliably.

Set AGP_VERSION

That fixes this error:

Add androidx.test:runner deps

That fixes this error:
