[bug] Closing windows does not emit WindowEvent::Destroyed

[UserVeryUnknown]

Describe the bug

In a previous version a secondary window that I created emited the WindowEvent::Destroyed event when closed. I just upgraded to 1.0.0-rc.4 and here the event seems not being emitted.

Reproduction

https://github.com/UserVeryUnknown/test-tauri-2win

The application consists of a main window with a button to open a second window. Once it is open there are 2 ways closing the 2nd window, either by the button on the 1st window or clicking the X on the 2nd window. Both do not trigger the event handler. But e.g. moving the windows does (so the event handler is working).

Expected behavior

When closing the window the WindowEvent::Destroyed should be emitted.

First step for the fix: tauri-apps/tao#349

I'll open the Tauri PR in a bit.

[lucasfernog]

Also tauri-apps/tao#350 is needed for this.

@lucasfernog : I just built against the rc5 and I still have the same issue!

[lucasfernog]

My bad I just found the regression. Fixing it atm.
