Emulator helper so tests start in seconds, not minutes

The Google TV emulator was launched by hand with -no-snapshot, which forces
a cold boot every time. tests/helpers/emulator.sh boots from the AVD's
default_boot snapshot (~7s) and refreshes that snapshot on stop, so the next
run stays fast. It also wraps the two things a test run needs afterwards:
installing an APK and pulling a screenshot into tests/runs/.

CONTEXT.md's example dialogue still described Xtream credentials entered
through the Remote, which ADR-0005 and ADR-0007 replaced with device flow and
phone-side onboarding.
