Description of the Change

There's an issue when Wordpress doesn't use the year/month file structure in the uploads folders, when trying to upload intermediate images to the container, $upload_folder_path is wrongly set to / ./ and that causes the image doesn't get uploaded and by consequence, just the original file is getting uploaded correctly.
By checking if the option is disabled we can set $upload_folder_path to / which fixes the issue

This fix closes #229

How to test the Change

• Go to Settings > Media and uncheck "Organize my uploads into month- and year-based folders" option
• Go to Media
• Upload an image
• Check the container
• All intermediate images should be there
