Router clears Options in the window.history.state

[nkrivous]

Bug report

Describe the bug

It seems that next-server router clears Options object from the window.history.state.

To Reproduce

1. store something in the window.history.state
2. refresh the page to recreate Router object
3. Options object is empty

Expected behavior

Router recreate Options in the window.history.state

Additional context

I've investigated that problem has its roots in the Router constructor
https://github.com/zeit/next.js/blob/canary/packages/next/next-server/lib/router/router.ts#L129
It calls method this.changeState(...) without passing Options object. And default value for Options is empty object {}.

window.history should not be manipulated outside of the router as that will cause the router to go into a bad state when using the back button.

Re-opened #771 because as of right now manipulating history is expected to break.
