Steps to reproduce:
1. Download latest attached project(oc link)
2. Build for Standalone
3. Go to the Plugins folder of the build

Expected result: only the single plugin .dll file is present
Actual result: an additional folder containing a dll of the same name is created

Reproduced on 2018.1.0a6, 2018.1.0a7, 2018.1.0b1, 2018.1.0f2, 2018.2.0b2, 2018.3.0a1
Not reproduced on 2017.4.3f1, 2018.1.0a1, 2018.1.0a4, 2018.1.0a5
Regression introduced in 2018.1.06

notes:
-On VR, this makes openvr_api.dll fail to load, leading to VR failing to start
-Temporary workaround - go to the build's plugin folder and delete the x86_64 folder

FIXED 2018.2.5f1
