fix(htmlAnchorDirective): don't add event listener if replaced, ignore event if target is different element

Previously, when an `a` tag element used a directive with a replacing template, and did not include an `href` or `name` attribute
before linkage, the anchor directive would always prevent default.

Now, the anchor directive will not register an event listener at all if the original directive is replaced with a non-anchor, and
will ignore events which do not target the linked element.
