[mv3] Fix conversion of `:xpath` procedural filters

Procedural filters with `:xpath` operator were silently rejected
at conversion time because the parser was failing to evaluate the
xpath expression due to the absence of a `document` object in
nodejs.

If `document` object is not present, the parser will assume the
xpath expression is valid.
