Fix for single-process WebUI transition CHECK failure.

Fix for single-process WebUI transition CHECK failure.

Don't ensure, in single-process mode, that WebUI render views are the only ones in the process, as it makes no sense  - we have single process only and no process-separation is expected.

This allows testing navigation between WebUI and standard pages
in single-process mode.

Hi nasko,

this is a reland of https://codereview.chromium.org/298133002/ as suggested by
sergiyb in the comment there.
Could you please rubberstamp this for landing?

Few things before that:

* How is this different than when it broke the memory bots?
* Can you update the patch title to be shorter (limit to 80 chars)?
* Please drop the Committed:/Cr-Commit-Position part of the description, as it
only applies to the old CL and this one will get its own once it is committed.

From what I understood this patch was reverted tentatively as a part of the
range of commits between test runs or did I misinterpret it?
This was just an another attempt to land it believing this one is not the one to
break as this does nothing but disables the CHECK
for single-process mode which does not apply there.
