Change/Fix: (org-ql-view--format-element) Use org-ql--tags-at

Use org-ql--tags-at instead of org-get-tags/org-get-tags-at.  This
uses our cache, which should improve performance, and it obviates the
function alias for Org versions before 9.3 (which occasionally
misbehaves, e.g. if Org is reloaded).
