      What happened?

      Goals

      I am attempting to use a Realm in a Hololens application

      Expected Results

      The Realm works in-editor and on device

      Actual Results

      it fails on device with a DLLNotFoundExeption for realm-wrappers.dll,

      Repro steps

      Add Realm and the Mixed Reality Tool Kit to a Unity project, and configure for deployment to a Hololens. In a script attempt to get a Realm instance. Observe that the realm is accessible in-editor. Using the MRTK build window, build the unity project and then the .appx, and deploy it to a Hololens. In the logs you should see a DLLNotFoundExeption for realm-wrappers. I've uploaded a project that minimally reproduces the issue here: https://drive.google.com/file/d/1GLUrmeRzhD7QuhiUmuQadj16onyAXS_X/view?usp=sharing
