Fix divergent equals and hashCode behavior

Calling Objects.hash with a byte[] will call the identity hashCode on
the byte[] and this doesn't agree with the use of Objects.deepEquals
in equals.
Bug caught by error prone.

Also, replaced usage of Objects.deepEquals(mServiceDataUuid, ...) with
Objects.equals(mServiceDataUuid, ...), because mServiceDataUuid
is an Object of type ParcelUuid.
