    Initiate deletion of image files if the import was interrupted
    
    If the image is deleted by appropriate API call while its content
    is still being uploaded in import task in v2, an exception is raised
    and it is not handled in the API code. This leads to the fact that
    the uploaded image file stays in a storage and clogs it.
    
    There existed code that safely removes image files if the exception
    occurs.
