We have to make sure that the plugins to be tested are located inside
the virtual sandbox / relative to the application binary. Launching via
winrtrunner, a test can find those plugins then. It is not possible to
those via TESTDATA and extract them to temp, as LoadPackagedLibrary only
loads inside the sandbox.
Unfortunately this also implies that running those tests inside Visual
Studio will fail, as Visual Studio copies the virtual sandbox to another
location missing the plugins. For automated testing this should not
matter though.
