Forbid to encrypt or decrypt a non-empty folder.

The specs forbid the encryption or decryption of a
non empty folder. so...
1 - check for the sync status, if it's not synced return

as there's no way that I can say that there's items on the
server right now without waiting for the sync to finish

2 - verify if the folder is empty locally

as the user could have send some files to the folder.
