[AC-4810] Android: view.center not working

Android: view.center not working. 6.0.1.GA is affected!!! *Steps to reproduce:* * Create an alloy project with the reporter's provided test case * Run the app * Change the value of the x and y axis of the center by tapping on red rect * Observe that no change takes effect *index.js:*

function onClick(e) {
    $.testView.center = {
    	x: '50dp',
    	y: '50dp'
    };
}
$.win.open();

*index.xml:*

<Alloy>
    <Window id='win' backgroundColor="green">
		 <View id='testView' backgroundColor="red" width='100dp' height='50dp' onClick="onClick" />
    </Window>
</Alloy>

P.S. iOS works fine.
