[bug] Error in tauri.conf.json crashes dev server

[madflow]

Describe the bug

An invalid value tauri.conf.json when running yarn run tauri devcrashes the dev server.

thing ➜ yarn run tauri dev
yarn run v1.22.19
$ tauri dev
`tauri.conf.json` error on `tauri > windows > 0 > height`: The value must be number
error Command failed with exit code 1.
info Visit https://yarnpkg.com/en/docs/cli/run for documentation about this command.

When trying to run yarn run tauri dev again - there is still a process running.

➜  yarn run tauri dev
yarn run v1.22.19
$ tauri dev
     Running BeforeDevCommand (`yarn dev`)
        Info Watching /xxx/src-tauri for changes...

Error: Port 1420 is already in use
    at Server.onError (file:////xxx/node_modules/vite/dist/node/chunks/dep-665b0112.js:52451:28)

The current fix is ps aux and kill.

Reproduction

• I have create a new project with yarn create tauri-app.
• I have selected the vanilla-ts template
• I have installed all deps with yarn
• Start yarn run tauri dev
• Change the windows height in tauri.conf.json to an invalid value ("abc") and save

Expected behavior

I would expect a better developer experience. Either the dev server should exit cleanly or I should be able to kill all running processes with "tauri"

In my case (under Mac OS 11.4.0 X64), although the port is not occupied,but the original app has not been terminated. After change invalid number into a valid number, the new app process will be enabled on the new port, and I will get two apps.
