Subject: [PATCH] Add null check to `ExoPlayerImpl.isTunnelingEnabled`

`TrackSelectorResult.rendererConfigurations` can contain null elements:
> A null entry indicates the corresponding renderer should be disabled.

This wasn't caught by the nullness checker because `ExoPlayerImpl` is
currently excluded from analysis.
