Reproduction steps:
1. Create new project
2. Build to iOS platform
3. Open Xcode project
4. Open "Classes/Preprocessor.h" code
5. Notice that "UNITY_USES_REMOTE_NOTIFICATIONS" is by default set to 1:
#define UNITY_USES_REMOTE_NOTIFICATIONS 1

Expected behaviour: "UNITY_USES_REMOTE_NOTIFICATIONS" should be set to 1 only if it is required for the project.
Actual behaviour "UNITY_USES_REMOTE_NOTIFICATIONS" is set to 1 by default.

Reproduced on versions: Unity 5.4.4p4, 5.5.2p1, 5.6.0b10, 2017.1.0a2
Unity 5.3.7p4 build did not have "UNITY_USES_REMOTE_NOTIFICATIONS" defined at all.
