Revert of Disable OriginReplicationAllowsAccessToStorage test.

Revert of Disable OriginReplicationAllowsAccessToStorage test. (patchset #1 id:1 of https://codereview.chromium.org/1030883003/)

Reason for revert:
RenderWidgets should be cleaned up properly now.

Original issue's description:
> Disable ChromeSitePerProcessTest.OriginReplicationAllowsAccessToStorage test.
>
> The test sometimes triggers a shutdown race condition that results in
> a UAF in blink::FocusController::focusedOrMainFrame() in the renderer,
> due to WebFrameWidgetImpl outliving Page.  Disabling the test until
> this is fixed.
