Use the right escape value when creating the pagination searcher

[jorgelbg]

When calling searcher.pager() for the Solr service the newly returned searcher was always using defaultSolrConfig as config options, ignoring the escapeQuery option.

Most of the time this is not an issue because queries are escaped by default. I hit this issue while using quepid with a query like field:(term), and the second batch of results would use the escaped query: field\:\(term\).

This causes that while the first page loads the desired results. If we navigate to the second page a potentially different result set would be returned.

Rolling in Quepid 6.2 if you want to confirm the fix when I release it today!
