[bug] Port does not close if window closed.

[bicarlsen]

Describe the bug

It appears that the port does not close if the tauri app is closed form the window close button rather than the command line.

Reproduction

1. Start tauri in dev mode, e.g. yarn tauri dev
2. Close the app window with the close button rather than terminating the process in the command line. The command line process terminates as well
3. Start tauri in dev mode again, it now asks to use a different port because the original one is in use.

Expected behavior

Port should close when process terminates, regardless of how it terminates.
