Fixed a bug regarding changes around headless emulator initialization: Start device is failing #16
Background:
The binary emulator-headless is now retired. Headless builds of the engine are now launched via emulator -no-window, thus unifying the previously separate (but similar) paths.
(Android Studio Release Updates: Emulator 29.2.11 and AMD Hypervisor 1.2 to Stable)
Thanks for @dweekly for the contribution!
