tdf#82744: fix WebDAV lock/unlock behaviour - part 4

Fix a problem when neon send the token list for
methods modifying a WebDAV resource.

The problem showed up when working whith Sharepoint 2013.
Other WebDAV servers seem unaffected by it.

The If Request Header is currently formed in neon using the
"Tagged-List" format, while Sharepoint 2013 only accepts the
"No-Tag-List" format.
