Don't call `updateDiff()` in the Revisions FrameState model.

* Stuff needs to hook in, so firing it early results in a half-rendered screen.

* Now, in the frame view's `render()`, it calls `updateDiff()`, relying on its promise.

See #24425.

Use maybe_unserialize() in upgrade.php's private get_option() function. This actually predates maybe_unserialize() ([2487], [3234]). props leewillis77. fixes #24365.
