Discard hidden articles when using fast path

Dom Distiller returns an empty content string for certain webpages.

The shortcut logic that Dom Distiller uses when some pages have one or
more <article> or <element itemscope itemtype="Article"> can lead to
erroneous content.

Some web pages have hidden articles, and these are being considered as
valid elements.

In order to fix this, when Dom Distiller is searching for article tags,
it will now discard hidden article elements.
