These are mostly mechanical changes to replace usage of `testHasValue`
with `testGetValue`.
`testGetValue` will now return `null` instead of throwing an exception
if no data is available.
To lighten-up our memory usage and startup performance, all of the RecentlyClosed
machinery was converted to use a light-weight TabState - specifically, it's missing
EngineSessionState, which is expensive to obtain during startup, and potentially
very costly to keep in-memory.
When we actually need EngineSessionState (at the point of restoration of a tab), we
read and rehydrate it using provided storage implementation.
