Reproduction steps:
1. Open the attached project;
2. Build project to device;

Actual result: an error "Please enable Daydream or Cardboard in Player Settings" shows up.
Expected result: an error should not show up because in Player Settings VR SDK is set to Daydream.

Note: an error should be related with GoogleVR -> Editor -> GvrBuildProcessor.cs.

Reproduced with: 5.6.0b5, 5.6.0f1, 5.6.1p1, 2017.2.0a1
Not reproducible with: 5.6.0b1, 5.6.0b4
Regression introduced in 5.6.0b5

Cannot be tested with 5.6 alpha and older versions because it does not support Daydream
