Enable error pages for layout tests.

Enable error pages for layout tests.

Currently, we remove error page navigation for layout tests, which means
that we have strangely divergent behavior in some edge cases. This patch
removes that special-casing and fixes up tests that depended on the edge
cases.

WDYT, Jochen? Checking for layout-testness up here doesn't make much sense
regardless, but perhaps you know of some reason that error pages were carved
out?

Blink relies on the embedder for error pages, and drt just didn't implement it,
and content shell intended to match drt

So look lgtm
