BUGFIX Use current ziggy instance in current method

When there is no global Ziggy instance, for example when not useing the blade directive and bundling the lib with webpack, there is not a global Ziggy, so when one calls `route().current()` it fails as this method instantiate a new `Route` instance without passing a Ziggy instance.
