save_email_file not return Path return TRUE

**Describe the bug**
```
from msg_parser import MsOxMessage
msg_obj = MsOxMessage(msg_file_path)
json_string = msg_obj.get_message_as_json()
msg_properties_dict = msg_obj.get_properties()
saved_path = msg_obj.save_email_file(output_eml_file_path)
```
Instead, of returning the saved_path it returns TRUE.
