bug: mobile: e2e: sign-in tests fail on Android

[ericswpark]

What happened?

On Android, signing in fails due to a synchronization issue with Detox.

What can we do to reproduce the problem?

Run the sign-in E2E test with Detox, on Android, using the command:

npx detox test --configuration android.att.debug signin-screen.test.js

Relevant log output

This has been "fixed" with a workaround for now that adds a delay, but I'm keeping this issue open until there's an official patch from upstream.
