herbstluftwm: Fix error when no tags set

Browse source 
The default value for `xsession.windowManager.herbstluftwm.tags` is an
empty list, but the config file uses `builtins.head` on it, which causes
an error upon evaluation. With this change the tags configuration is
skipped if the list is empty.
