Improve remove method and add more tests for BungeeJsonFile class

- Handle single-part paths in `remove` method
- Add test for removing a key and verifying remaining keys
- Add test for removing a non-existent key
- Add test for removing a nested key
- Add test for removing all keys in a node
- Add test for verifying keys after all values are removed
