Bug in error message from snapshot listener #1085

Query Listeners in the combination of whereGreaterThan and whereNotEqualTo filters is throwing an exception as expected but with a small bug in the error message where it says com.google.cloud.firestore.FirestoreException: Backend ended Listen stream: Cannot have inequality filters on multiple properties: name with only mentioning one field property whereas with other combinations the message was correct mentioning exactly what all the multiple properties were.
