Support unsetting check URLs

Setting a check URL to an empty string should unset the check URL.
That's what we do for checker URLs too.

Also make the population of CheckUpdate in PostCheck consistent with how
CheckerUpdate is populated in UpdateChecker. This makes a bunch of
methods in CheckUpdate unneeded.
