newline char(\n) in stop param leads to 500 error in gpt-3.5-turbo

[wonkyuml]

Describe the bug

unlike text-davinci-003 model, gpt-3.5-turbo model fails when using stop='\n'.
maybe it would be backend problem but it would be good to have front-end translates '\n' into some form that backend server can deal with.

To Reproduce

with openai(0.27.1) package
running this line of code would result in 500 error.

Code snippets

completion = openai.ChatCompletion.create(
  model="gpt-3.5-turbo",
  messages=[{"role": "user", "content":"hello"}], 
  stop=['\n']
)

### OS

Ubuntu 18.04

### Python version

Python3.7.15

### Library version

v0.27.1

Give this a try:
completion = openai.ChatCompletion.create(
model="gpt-3.5-turbo",
messages=[{"role": "user", "content":"hello"}],
stop=[r"\n"]
)

This worked for me.

stop=[r"\n"] does not result in 500 error but it does not stop model generating multiple-lines of text.
