[java-firestore] use Emulator with Firestore without credentials

Hi

based on the existing issues on the repo and the latest 2.0.0 release i understand that its suppose to be possible to connect to the FireStore emulator without providing a real credentials, as its not really needed.

i've tried to do the following

Firestore FS = FirestoreOptions.getDefaultInstance().toBuilder()
.setProjectId("test")
.setHost("localhost:8888")
.setCredentials(EmulatorCredentials())
.setCredentialsProvider(FixedCredentialsProvider.create(EmulatorCredentials()))
.build()
.getService();

using the latest 2.0.0 java-cloud-firestore.
but, it doesnt seems working and i still get the exception that asks me to provide GOOGLE_APPLICATION_CREDENTIALS.

what am i missing?

i also saw there was another merge on that area, and the additional .setEmulatorHost to the FireStoreOptions but it was not yet published.

thanks,
Chen
