Prerender: remove possible race in browser tests to improve flakiness.

Prerender: remove possible race in browser tests to improve flakiness.

There may be a race condition that causes flakiness in the form of timeouts in
several prerender browser tests involving waiting for prerender contents to be
created. As I have not been able to reproduce the flakiness locally, I'm not
sure this is actually a fix for the flakes. Fingers are crossed and wood is
being knocked.

LGTM

since it is a slight complication, can you add a TODO to revert it if the
flakiness is not fixed? Referencing the bug in the TODO would be helpful.

Discussed offline, the paranoia is probably the right programming practice to
use in any case.
