#1204 Add (or enhance) test for SmalltalkImage >> readJSObject:

Originally at 2015-09-22T10:29:23Z by Herbert Vojčík Recent fix fixed readJSObject in boot.js to be able to cope with `null` / `undefined` present inside read objects. This is exposed in Smalltalk side as `Smalltalk readJSObject: ...`. There should be unit tests for this (which maybe are there already), including the case of `null` / `undefined` present inside objects (which is provably not there, or the tests wouldn't pass before the fix). <bountysource-plugin> --- Want to back this issue? **[Post a bounty on it!](https://www.bountysource.com/issues/26863635-add-or-enhance-test-for-smalltalkimage-readjsobject?utm_campaign=plugin&utm_content=tracker%2F79201&utm_medium=issues&utm_source=github)** We accept bounties via [Bountysource](https://www.bountysource.com/?utm_campaign=plugin&utm_content=tracker%2F79201&utm_medium=issues&utm_source=github). </bountysource-plugin>
