[TIMOB-25565] Android: Prevent auto-focus callback from taking multiple pictures

[garymathews]

• Prevent auto-focus callback from taking multiple pictures (once each time of focus)
• Remove auto-focus callback after focusing

NOTE: this only occurs on some devices, such as the Moto G4

TEST CASE

var win = Ti.UI.createWindow(),
    view = Ti.UI.createView(),
    btn = Ti.UI.createButton({
        title:'TAKE PICTURE',
        bottom: 10
    });

function showCamera () {
    Ti.Media.showCamera({
        autohide: false,
        saveToPhotoGallery: true,
        overlay: view,
        success: function (e) {
            Ti.API.info('path: ' + e.media.nativePath);
        }
    });
}

// add button to overlay
btn.addEventListener('click', function () {
    Ti.Media.takePicture();
});
view.add(btn);

// request permissions and show camera overlay
win.addEventListener('open', function () {
    if (Ti.Media.hasCameraPermissions()) {
        showCamera();
    } else {
        Ti.Media.requestCameraPermissions(function (e) {
            e.success && showCamera();
        });
    }
});

win.open();

FR Passed.

Success callback is fired only once on android 7.1.1 & 6.0.1. Asked the customer to check on his Moto G4 (as we do not have the device) & it works fine for him.
