Description

enhancement type:bug

Describe the bug

When running multiple tests that are using GraphServiceClient every second test is failing with "RuntimeError: Event loop is closed".
When changing scope of test to "module" tests are working properly.

Expected behavior

GraphServiceClient can be used in pytest tests with test scope=="function".

How to reproduce

import pytest
from azure.identity import AzureCliCredential
from msgraph import GraphServiceClient

@pytest.mark.asyncio()
async def test_1():
    with AzureCliCredential() as credential:
        client = GraphServiceClient(credential)
        me = await client.me.get()

@pytest.mark.asyncio()
async def test_2():
    with AzureCliCredential() as credential:
        client = GraphServiceClient(credential)
        me = await client.me.get()

SDK Version

1.4.0

Other information

In my opinion it is connected to GraphRequestAdapter and GraphClientFactory.create_with_default_middleware - After I've modified client parameters to be None by default and then creating clients if needed within the function body it started working properly.
