.find() function does not work after a single use

Describe the bug When writing data to the JSON db, after the first write to the file, the .find() method will return the record based on the ID. After adding a 2nd record and trying again, the IdNotFoundError error is thrown despite the record being in the DB!

How to reproduce python 3.9.6

from pysondb import db

if __name__ == "__main__":
    db = db.getDb("test.json")
    while True:
        id = db.add({"dev": "test"})
        print(db.find(id))

Expected behavior The record should be returning as expected.

This is a neat library, great work!
