Files still get downloaded from "unsubscribed" folder

Even if a folder is unsubscribed the files uploaded to that folder via web ui or different client get downloaded locally thus defeating the purpose of unsubscribing from a folder.

STR:

1. Create a new udf, say, ~/zomg
2. Verify that it was created - u1sdtoll --list-folders
3. Unsubscribe that UDF - u1sdtool --unsubscribe=$folder_id_of_zomg
4. Verify that ~/zomg is unsubscribed - subscribed=False
5. Go to https://one.ubuntu.com/files/ , zomg UDF and upload a file
6. Wait for the file to be uploaded, observe the file to be created locally

Even if you physically move the folder to another name, syncdaemon will want to download the file and fail with:
