MediaWiki does not treat [[]] or [[|...]] as wikilinks because their
title is empty. Calls to filter_wikilinks() on text containing these
sequences returned false positives.

The fix is in builder.py (pure Python, runs for both the C and Python
tokenizers): when a WikilinkClose token is encountered and the resulting
title is an empty string, the node is demoted to a plain Text node
containing the original bracket sequence instead of being wrapped in a
Wikilink.

Fixes #292.

PyList_SetItem steals the item reference even on failure, so the error path must not call Py_DECREF on the same object.
