wired-card calls non-existing this._requestRender()

[balloob]

<wired-card> calls this._requestRender() when the slotchange event is fired. However, that method does not exist on the elemnt.

<wired-card> depends on Lit Element ^0.5.1. I've checked the source code of Lit Element, and it looks like they renamed it to this.requestRender():

https://github.com/Polymer/lit-element/blob/fb90e7640777cab01c9eac2006cde558c34b041d/src/lit-element.ts#L261

(I did a quick search and noticed a few more places that call _requestRender().

I was using <wired-card> by importing it form unpkg:

<script type='module' src='https://unpkg.com/wired-card@0.6.0/wired-card.js?module'></script>

Sure enough, lit-element changed their API in 0.5.2 and that version is getting picked up. They should have used 0.6 for breaking changes fo semVer to work.
In the short term, if you can explicitly depend on lit-element 0.5.1, you may avoid running into this issue.

Resolved by upgrading to latest lit-element and adjusting code accordingly:
#32

Fix in v0.6.5
