[TIMOB-14576] BlackBerry: Can not return deferWidth or deferHeight to true if width or height is initially fixed value type.

In NativeControlObject to be able to front-end the layout engine when width or height is adjusted by margins some flags control how width and height are processed. The problem is when a width or height value is of type "fixed" for example a width: 50, height: 50 like for labels, buttons, and defer type controls then the deferWidth or deferHeight is set to false and can not be set back to true. The fix is to evaluate the width, height top and bottom property and reset if it's "SIZE" or the width or height is to be calculated by the engine.

int NativeControlObject::setWidth(TiObject* obj)
{
	string str = *String::Utf8Value(obj->getValue());

	if (str == "auto") {
		return NATIVE_ERROR_OK;
	}

	if (deferWidth_ && str == "UI.SIZE") {
		deferWidthType_ = Size;
		return NATIVE_ERROR_OK;
	}

	deferWidth_ = false;
	updateLayoutProperty(Width, obj);

	return NATIVE_ERROR_OK;
}
