Expected behaviour

Nextcloudcmd completes a sync.

Actual behaviour

Nextcloudcmd sees that it is deleting the last file in a folder, issues a message:

04-15 20:05:02:389 [ info nextcloud.sync.engine ]: All the files are going to be changed, asking the user

and then hangs. No matter what the setting of --non-interactive.

This is new behavior in 3.2.

Steps to reproduce

1. Add a file to a folder
2. Sync it with nextcloudcmd
3. Delete the file on NextCloud instance
4. Run nextcloudcmd to sync it
5. Watch it hang

Still an issue with 3.2.2

[leafonthewind]

Getting this same hanging behavior. Attempted both with and without --non-interactive.

06-24 14:40:03:499 [ info nextcloud.sync.engine ]: All the files are going to be changed, asking the user

Steps:

1. Delete or move everything out of a folder.
2. Attempt to sync it back to Nextcloud.
3. Hangs. No files are changed on the server side.
