fix JENA-1439  graph queries fail 'lang:xx'

Fixes JENA-1439 graph queries fail to preserve text:query 'lang:xx' arg. 
TextQueryPF.extractArg(...) removed the arg unnecessarily from the input list, 
side-effecting the list which was saved in an OpPropFunc for repeated use on 
graph iterations and thus the argument was only present on the first graph in 
the iteration

> Jena-text queries that iterate over graphs, such as:
> {code}
>     select ?g ?s ?lit
>     where {
>        graph ?g { (?s ?sc ?lit) text:query (skos:prefLabel "one" "lang:xx") } 
> .

> {code}
> fail to pass the {{lang:xx}} after the first graph leading to erroneous 
> results.
> A file with configuration, query, trace logging and results is attached along
