Bug description

if a local folder is ignored (i.e. the name matches ignore patterns), the desktop files client will not sync it to the server.
in files explorer, the status icon will be empty (i.e. no status icon)
once you rename it such that it will be synced to the server, the content of the folder will be deleted

Steps to reproduce

1. Create a new folder
2. Rename it to testIgnore
3. Add some files inside it
4. Wait for sync to happen
5. Free up storage such that the new not empty folder gets a cloud status icon
6. Add a rule to ignore all items with pattern: *.msg
7. Rename testIgnore to testIgnore.msg
8. Wait for sync to happen
9. Rename testIgnore.msg to testIgnore
10. Wait for sync to happen
11. Checks the content of the folder

Files stored in this folder (or in its sub-folders) are not deleted
