feat(android): add getLastLocation to FusedLocationProvider

[m1ga]

JIRA: https://jira.appcelerator.org/browse/TIMOB-26675

Optional Description:

Had this old ticket in my queue. Might fire the location event quicker. Implementation from: https://developer.android.com/training/location/retrieve-current#java Not sure how to test it :smile:

example

var win = Titanium.UI.createWindow({
	layout: "vertical"
});

Ti.Geolocation.accuracy = Ti.Geolocation.ACCURACY_HIGH;

function getLocation() {
	Ti.Geolocation.addEventListener('location', function(e) {
		console.log(JSON.stringify(e, null, 2));
	});
}
win.addEventListener('open', function() {
	if (Ti.Geolocation.hasLocationPermissions()) {
		getLocation();
	} else {
		Ti.Geolocation.requestLocationPermissions(Ti.Geolocation.AUTHORIZATION_ALWAYS, function(e) {
			if (e.success) {
				getLocation();
			} else {
				alert('could not obtain location permissions');
			}
		});
	}
});

win.open();
