Bugfix/n3 format

[ylebre]

This changes the format for multiple lines so that the middle line has a ; on the end instead of a '.';

It goes from

@prefix solid: <http://www.w3.org/ns/solid/terms#>.
<#foo> a solid:InsertDeletePatch;
  solid:deletes { <#hello> <#linked> <#world> .}.
  solid:inserts { <#hello> <#linked> <#world> .}.

to

@prefix solid: <http://www.w3.org/ns/solid/terms#>.
<#patch> a solid:InsertDeletePatch;
  solid:deletes { <#hello> <#linked> <#world> .};
  solid:inserts { <#hello> <#linked> <#world> .}.
