Use _fakeStop when present instead of fakeStop for older versions of Leaflet.

Checks for presence of old _fakeStop method. If it's available, use it instead. If not, use the new fakeStop.

Just to add why this is necessary: while this library works fine on older versions of Leaflet otherwise, the call to fakeStop breaks functionality with click events and etc. The fakeStop method is the same as the _fakeStop method in previous versions, it was just renamed to fakeStop in newer Leaflet releases.
