`ionic cordova` wrapping swallows "Terminate batch job (Y/N)?" prompt, causing e.g. `cordova run` processes to not really stop and cause increasing port numbers to be used

Compare what happens when you hit Ctrl + C when running `ionic cordova run ...` vs. when running `cordova run ...`:

On the pure `cordova` command you get an additional prompt:
```
^CTerminate batch job (Y/N)? y
```

When you immediately run the same command again after killing it, it should just start a server again on the same port, `8000` by default. But with `ionic cordova ...` you get increasing port numbers:

```PS C:\Projects\Ionic Demo Projects\browserTest2> ionic cordova run browser
Running app-scripts build: --platform browser --target cordova
[23:04:40] build dev started ...
...

```

vs.

```
PS C:\Projects\Ionic Demo Projects\browserTest2> cordova run browser
startPage = index.html
Static file server running @ http://localhost:8000/index.html
CTRL + C to shut down
200 /index.html (gzip)
...
404 /screen
^CTerminate batch job (Y/N)?
^C
PS C:\Projects\Ionic Demo Projects\browserTest2> cordova run browser
startPage = index.html
Static file server running @ http://localhost:8000/index.html
CTRL + C to shut down
304 /index.html
...
404 /screen
```

That this "Terminate batch job" prompt is important can be deduced from what happens when you first run `ionic cordova run` with increasing port numbers, then `cordova run` once with another +1 port and kill it with the prompt, after that the next run will get the initial port number again:

```
...
PS C:\Projects\Ionic Demo Projects\browserTest2> cordova run browser
startPage = index.html
Static file server running @ http://localhost:8003/index.html
CTRL + C to shut down...
^CTerminate batch job (Y/N)?
^CThe system cannot open the device or file specified.
PS C:\Projects\Ionic Demo Projects\browserTest2> cordova run browser
startPage = index.html
Static file server running @ http://localhost:8000/index.html
CTRL + C to shut down
...
```

未指定檔案或測試。比較 `ionic cordova run browser` 與 `cordova run browser`，在 Windows 上重現 Ctrl+C 的行為，然後追蹤 Ionic CLI 如何包裝 Cordova 程序。完成標準是處理終止提示，且重複執行時重新使用連接埠 8000，而不是遞增連接埠號。
