CoreNLP server doesn't close when using with-statements

Describe the bug The CoreNLP server is not stopped automatically after the with statement in Python is finished. This happens during interactive Python sessions and running Python scripts as a whole. The server will close itself if the terminal session is closed.

To Reproduce Steps to reproduce the behavior:

Write


from stanza.server import CoreNLPClient

if name == "main": text = "Chris Manning is a nice person. Chris wrote a simple sentence. He also gives oranges to people." with CoreNLPClient( annotators=[ "tokenize", "ssplit", "pos", "lemma", "ner", "parse", "depparse", "coref", ], timeout=30000, memory="6G", ) as client: ann = client.annotate(text)

2. Run this code as a script in the terminal
3. Run this code again as a script in the terminal
4. See error

***Second situation***
1. Write the same code.
2. Run the code interactively using `python -i`
3. Call `client.stop()`

**Expected behavior**
The server is supposed to be closed at the end of the script or upon calling `stop()`, according to this [demo](https://colab.research.google.com/github/stanfordnlp/stanza/blob/master/demo/Stanza_CoreNLP_Interface.ipynb#scrollTo=W435Lwc4YqKb).

**Environment (please complete the following information):**
 - OS: Win 11
 - Python version: Python 3.9.5 from Anaconda
 - Stanza version: 1.3.0

**Additional context**
I am running this inside VSCode.
