XDG save_config_path raises FileExistsError

[krisgesling]

Describe the bug
The pyxdg save_config_path ensures that a directory exists before using it. This is done using os.path:
https://github.com/takluyver/pyxdg/blob/master/xdg/BaseDirectory.py#L57-L58

Based on the Traceback below I'm wondering if we have items starting in separate threads, that are both checking/creating the XDG paths.

Traceback (most recent call last):

FileExistsError: [Errno 17] File exists: '/home/mycroft/.config/mycroft'

I haven't yet found other projects hitting the same issue.

Expected behavior
Create the directory if it doesn't exist, otherwise just use it.

Environment (please complete the following information):

• Device type: Mark 2
• OS: Mark 2 build dated 2021-11-25 15:34
• Mycroft-core version: 21.2.1
• pyxdg v0.26

I hit this issue with docker containers and flagged it back then, i recommended to use xdg_data_home instead of save_data_dirs etc.

A string definition should be a string definition, not create paths automatically on import

Sorry for missing / forgetting about that @JarbasAl. That is definitely a better way to handle it.
