JENA-2273: Fix ASK in ResultSetWriterCSV and -TSV

Small problem - that code isn't being called.

There is a migration going on from ResultSet to RowSet as the basic for the machinery. RowSet works exclusively at the Node level.

Line 82 in d3fe7bb

if ( false ) {

The registration of the ResultSet version is if/false'd out.

ResultSet objects are now an adapter to the RowSet version from package org.apache.jena.riot.rowset.rw as of jena 4.4.0. The code looks very similar.

One style point (which ought to apply to the existing code) on try-finally.
Some tabs are used instead of spaces.
Github display means spaces work better across everyone's views.

As long as we're clear this is technically an extension to the standard!

Both RowSetWriters had the same problems, and I added a commit that fixes them (and adds the same test classes).

I've pulled PR and it all works, command line and in Fuseki but the build itself fails because of missing Apache License headers on new files.

Sorry for not spotting this earlier.

It is the same header as a file you've modified.
Touching license headers is something to be done by the contributor, not the project else I'd have fixed them.

I'll leave it up to you whether you want to squash the PR to a single commit or not.

I've added the license headers and squashed the commits.
