get return last known value

[unional]

If there are getProperty invoked during simulation but there are not more recorded get action, the last value should be returned.

It is possible that during simulation it tries to make more get (or the get was not recorded some how during save)

[unional]

  // console.log(tyepof res.data) // string
  if (!res.data) return []
  if (res.data) return []
  console.log('what!!', typeof res.data) // undefined

should be either strict (throws MissingAction) or return last known value.

If not, the result is very confusing and hard to realize

A problem is that there are a lot of extra calls made by system, TypeScript (e.g. look for .then),
library (e.g. @ungap/structured-clone looks for .toJSON. It is removed in 8.0),
and assertion library (e.g. jest's expect().toEqual() make extra checks that is hidden).

It is quite a hard thing to handle.
