Folder Setup: Allow to set up more sync connects to the same folder.

One local folder can now be configured as sync target for multiple
accounts as long as their url and user differ.

Also this patch accepts that the sync folder is behind a symlink.
Also this patch fixes a bug that before the user input was taken
canonically which was not working for the symlink handling.
