[TIMOB-25266] Android: Loading url in WebView crashes on Android 4.1

*Summary:* WebView will crash on Android 4.1 when it attempts to load a webpage. *Test:*

var window = Ti.UI.createWindow();
var webView = Ti.UI.createWebView(
{
	url: "https://appcelerator.com",
});
window.add(webView);
window.open();

*Notes:* - It does not crash on Android 4.2 or newer OS versions. - It won't crash on Android 4.1 if a webpage has not been loaded. (That is, the "url" has not been set.) *Cause:* It crashes when the Canvas.drawPath() methods get called in our "TiBorderWrapperView.java" while hardware acceleration is enabled. So, even though we've never applied a border in the above test code, our WebViewProxy always applies a zero border width to its settings, which is enough to trigger our TiUIView code to go wrap the WebView in a TiBorderWrapperView container. *Suggested Solution:* Never draw a border around a WebView on Android 4.1 to work-around this issue. Note that disabling hardware acceleration will work-around this issue as well, but doing so will prevent HTML5 videos from being seen (see: [TIMOB-23885]), making this a worse solution.
