Use get_avatar_url instead of get_avatar + SimpleXMLElement

Why do you use this fudge (your own words)?

The get_avatar_url() function was added in Wordpress 4.2. We wrote the plugin way before that.

ok but xml parsing is a bit overkill.

something like preg_match('/src="([^"]+)"/', $img, $match); would do.

xml parsing did cause a bug with vanilla user, it is expected a closing slash or something.
