Type error in runtime.js::handle_click for <a> without href

[samhatchett]

if no href is set in the client html - as in,

<a role="button" on:click="do_something()">click</a>

this results in a type error in runtime.js - because href will be null here:

sapper/src/runtime/index.ts

Line 167 in e60714b

const href = String(svg ? (<SVGAElement>a).href.baseVal : a.href);

You probably want to use an <button> instead, seen as you are defining the role as a button.
