Fix: (org-ql-view--format-element) Avoid unlinkifying links

I don't fully understand why this is the correct fix, because I don't
know where the raw heading text is being linkified (it seems like the
:raw-value property should be the unlinkified text), but this seems to
work correctly now.  If it turns out to break something else, we'll
find out and fix it.

Fixes #282.
