[TIMOB-2771] Android: Facebook publish stream does clear/reset its data

From Fred:

Login and tap 'Post 01'. Rather than submitting, close and tap 'Post 02' - It's using the same data from the first publish, even though the data is different in source. App data has to be completely cleared before this stops, but it continues to use the same publish data from the first publish request.

app.js:

var win = Ti.UI.createWindow();
var fbBtn = Ti.Facebook.createLoginButton({
    'style':'wide',
    'apikey':'9494e611f2a93b8d7bfcdfa8cefdaf9f',
    'sessionProxy':'http://api.appcelerator.net/p/fbconnect/',
    bottom:10
});

var post01Btn = Ti.UI.createButton({ title:'Post 01', left:10, right:10, top:10, height:30 });
var post02Btn = Ti.UI.createButton({ title:'Post 02', left:10, right:10, top:50, height:30 });

post01Btn.addEventListener('click', function(e) {
    if (Ti.Facebook.isLoggedIn()) {
        var data = {
            "name": "Sample Title 01",
            "href": "http://google.com",
            "description": "Sample Description 01",
            "caption": "Sent via a test Appcelerator App."
        };
        
        Ti.Facebook.publishStream("POST NUMBER 01", data, null, function(r) {                     
            if (r.success) {
                alert('Posted.');
            } else {
                alert('Not Posted.');
            }
        });
    }
});

post02Btn.addEventListener('click', function(e) {
    if (Ti.Facebook.isLoggedIn()) {
        var data = {
            "name": "Sample Title 02",
            "href": "http://google.com",
            "description": "Sample Description 02",
            "caption": "Sent via a test Appcelerator App."
        };
        
        Ti.Facebook.publishStream("POST NUMBER 02", data, null, function(r) {                     
            if (r.success) {
                alert('Posted.');
            } else {
                alert('Not Posted.');
            }
        });
    }
});

win.add(post01Btn);
win.add(post02Btn);
win.add(fbBtn);
win.open();
