[PATCH v3 1/6] amstream/tests: Fix AMMultiMediaStream::OpenFile test.

[Zebediah Figura]

From: Anton Baskanov

Fixes the following issues:
  - OpenFile failes on native with VFW_E_CANNOT_CONNECT as there are no renderes in the graph.
  - IMediaSeeking checks are called with a wrong object.
  - IMediaSeeking checks fail as there are no streams.

v3: Clean up the rest of the test while we're at it.
