Remove null string optimization from scm_from_stringn

Browse source 
* libguile/strings.c (scm_from_stringn): Always return a freshly
  allocated string from scm_from_stringn, even when asked to construct
  the null string, in accordance with the R5RS.  Previously, we
  optimized the null string case by returning a reference to a global
  null string object (scm_nullstr).
