fix: create_required_folders removes symlink to gcodes

What happened

I'm managing my printfiles on my nextcloud-folder.
~/printer_data/gcodes -> /home/pi/Nextcloud/printer_data/gcodes
This is folder is automatically synced via cron by issuing following command

nextcloudcmd   -n -s \
               --path 3dprint \
               ~/Nextcloud \
               https://nextcloud.example.com 

After installing moonraker-telegram-bot via your awesome script i've notices that my gcode files weren't available in telegram or fluidd.
Turned out that create_required_folders replaced my symlink gcodes -> /home/pi/Nextcloud/printer_data/gcodes with an empty directory.

What did you expect to happen

The symlink shouldn't be touched.
~/printer_data/gcodes -> /home/pi/Nextcloud/printer_data/gcodes

How to reproduce

• make ~/printer_data/gcodes as symlink
• install something
• check ~/printer_data/gcodes
