Relax the DOM UI navigation CHECK.

We ensure that non-DOM-UI URLs are not sent to DOM UI renderers.
This patch makes an exception for about:blank, which can happen
if the user gets the renderer to go to any about: URL (e.g.,
using the web inspector).

BUG=42547
TEST=Type location='about:cache' into NTP's web inspector, then Reload.
