Scraper fails when attempting to download an asset from the user running the script

[testtest1231234]

When assets are pulled the script attempts to get the models data associated with an asset in the ReformatManager class.

class ReformatManager:
...
    def prepare_reformat(self, media_item: MediaMetadata):
...
        # This is the method call that is that's failing since the author.id cannot be found in the `directory_manager_users` map
        download_path = self.filesystem_manager.get_directory_manager(
            author.id
        ).root_download_directory 
...

However it does not take into account that an asset can be owned by the user running the script, so an error occurs when attempting to find the author id in directory_manager_users.

For example, if the user sends a gif to a model, it is retrieved as an asset when scraping data and we run into the exception.

Forgive me for the poor formatting, I don't usually write Python so I'm not familiar with conventions for specifying files/classes/methods

Fixing the above issue should also fix these issues:

Can confirm this is the case for me for every model I have sent anything to.
