Make ScopedURLFetcherFactory sequenced-safe.
This CL allows ScopedURLFetcherFactory to be used in a test
environment exposing a sequenced task runner instead of
requiring a single thread task runner, a relaxation of the
requirements (single thread is a stricter instance of a
sequened task runner).
The URL fetcher code has already been relaxed in a previous
CL to only require a sequenced runner, but the corresponding
update to ScopedURLFetcherFactory was overlooked.
