Gabriel Charette a0e0846dbc Backport some tests in /content/browser to SingleThreadTaskEnvironment
These tests were previously migrated from single-threaded MessageLoop to
a multi-threaded TaskEnvironment (then named ScopedTaskEnvironment) as
part of crbug.com/891670.

//base OWNERS decided in retrospect that it was better to keep a
single-threaded option for TaskEnvironment and introduced
SingleThreadTaskEnvironment. This CL retrofits that decision for
/content/browser.

This CL is a no-op if it passes CQ.

This CL was uploaded by git cl split.
