Launch on fails during staging with a SafeCopyFile Exception for MfMedia.uplugin

Launch on fails during staging with a SafeCopyFile Exception for MfMedia.uplugin

Description

Was able to repro this on machines with and without machines set up for Xbone testing.

Steps to Reproduce

Repro:

  1. Create a template project.
  2. Open the project in UE4Editor and Launch on to your machine.

Result:
Launch on fails during the staging process due to:

 LogPlayLevel: InternalUtils.SafeCopyFile: WARNING: SafeCopyFile Exception was Exception in mscorlib: Could not find a part of the path 'D:\Epic Games\4.15\Engine\Plugins\Media\XboxOne\MfMedia\MfMedia.uplugin'.

Expected:
Launch on successfully completes.
