To reproduce:

1. Download and open attached "geardaydream.zip" project.
2. Build and run on android device which supports GearVR.

Expected result: Application launches in Selected VR SDK mode, in this case DaydreamVR mode, despite having OVRPlugin in the project.
Actual result: Application launches in GearVR mode.

Reproduced with: 2018.1.0a7, 2017.3.0f1, 2017.2.1f1, 2017.1.2p4, 5.6.4p4.

Devices under test:

Samsung SM G950U, OS:7.0, CPU:arm64-v8a, GPU:Adreno (TM) 540,
Build:samsung/dreamqltesq/dreamqltesq:7.0/NRD90M/G950USQU1AQC8:user/release-keys

Samsung SM G925F (Galaxy S6 Edge), OS:7.0, CPU:arm64-v8a, GPU:Mali-T760,
Build:samsung/zeroltexx/zerolte:7.0/NRD90M/G925FXXU5EQH6:user/release-keys

Notes: Oculus SDK is not included in the Supported SDKs list and it still loads GearVR. After deleting OVRPlugin under Plugins/1.20.0/Android everything works as expected. Same issue happens when Carboard is selected in supported VR SDKs.
