Create a testcase for Storage API assignment bug and file one for Chrome

[Manvel]

From #24

const setStorage = chrome.storage.local.set;
const getStorage = chrome.storage.local.get;

setStorage({key: value})

The assignment above causes the Error below in Chrome v70 on windows:

Function must be called on an object of type StorageArea

This seems to be a bug as it's not reproducible on Same version of Chrome on Mac and Chrome v69 had no complain either on both Mac and Windows.

This is a followup ticket to file the bug report for Chrome.

An issue was submitted, apparently this started to be reproducible on Chrome Dev v71 on MacOS as well.
