 * Installs a fake UAppData directory.

 * present in the test environment.
 *
 * We create the new UAppData directory under the profile's directory
 * because the profile directory is automatically cleaned as part of
 * test shutdown.
 *
 * This returns a promise that will be resolved once the new directory
 * is created and installed.
