[Downloads] Simplify DownloadContentTests.

There used to be two download resumption code paths. DownloadItemImpl
chose the applicable code path based on whether the WebContents that
initiated the download was still around. Now DownloadItemImpl
deterministically uses the no-WebContents code path. Hence the
parameterized tests that exercised both paths no longer need to do so.
