check with hasSize/hasMin etc fails with below error. Pydeequ version 1.0.0

**Describe the bug**
verificationSuite check with has fails with error -
Traceback (most recent call last):
File "/Downloads/spark-2.4.4-bin-hadoop2.7/python/lib/py4j-0.10.7-src.zip/py4j/java_gateway.py", line 2146, in start
OSError: [Errno 48] Address already in use

During handling of the above exception, another exception occurred:

py4j.protocol.Py4JNetworkError: An error occurred while trying to start the callback server (127.0.0.1:25334)

**To Reproduce**
Steps to reproduce the behavior:

check.hasSize(lambda x: x >= 100)

result = VerificationSuite(spark).onData(df).addCheck(check).run()

result_df = VerificationResult.checkResultsAsDataFrame(spark, result)

result_df.show()

Commencez par exécuter la reproduction signalée de hasSize avec Spark 2.4.4, Pydeequ 1.0.0 et Python 3.7, puis inspectez pydeequ/checks.py et pydeequ/scala_utils.py autour de ScalaFunction1 et du démarrage du callback-server. C’est terminé lorsque hasSize et les vérifications hasMin associées s’exécutent jusqu’au bout sans l’erreur Py4J d’adresse déjà utilisée et que le résultat de la vérification peut être affiché.
