Web Inspector: TextContentView calls the wrong super function in shown()
https://bugs.webkit.org/show_bug.cgi?id=135001

TextContentView calls ResourceContentView.shown instead of ContentView.shown.
It should call ContentView.shown because ContentView is its prototype.

* UserInterface/Views/TextContentView.js:
(WebInspector.TextContentView.prototype.shown):
