Splitting paths of Filters

[crisely09]

The query builder, SPARQLQueryBuilder.build method, uses Filter paths, which are supposed to be a list of paths, but one single string was given. This disables the possibility of identifying the id and type cases when they are given inside a long path.

The addition here is to split the path if there are any / in the provided path, so the id or type values are recognized.
