Bug description

nextcloudcmd --exclude doesn't exclude directory from sync. It still downloads the entire directory from server.
Ref: https://docs.nextcloud.com/desktop/latest/advancedusage.html#exclude-list

Steps to reproduce

1. Prepare a directory /InstantUpload on Nextcloud server. Put some files inside.
2. On desktop, create a txt file /tmp/list

InstantUpload
InstantUpload*
InstantUpload**
InstantUpload/*
InstantUpload/**
InstantUpload/*/*
/InstantUpload
/InstantUpload*
/InstantUpload**
/InstantUpload/*
/InstantUpload/**
/InstantUpload/*/*
*InstantUpload*

3. Run nextcloudcmd --exclude /tmp/list -u USERNAME -p PASSWORD https://my.nextcloud.site
4. Bug repro. It downloads the entire excluded directory.

Expected behavior

Nothing in InstantUpload directory should be downloaded or uploaded.
