Do not override the global page size when viewing/editing a saved search

After NXP-22016, when a saved search is edited (or viewed), the page size is set to 1 for the corresponding content view.

This is due to this line in /search/incl/tabs/savedsearch_document_edit.xhtml (or in /search/incl/tabs/savedsearch_document_view.xhtml)

<nxu:set var="contentView"
  value="#{contentViewActions.getContentViewWithProvider(currentDocument.cvd.contentViewName, currentDocument, null, 1, -1, -1)}"
  cache="true">

when the parameter which corresponds to defaultPageSize is set to 1

It should be set to -1 not to change the current page size.
