Rule DispatchNonShouldQueueToDispatchSyncRector will wrongly convert `dispatch` to `dispatch_sync` on Closures

[j3j5]

Laravel supports queuing closures using dispatch(). Currently the rule DispatchNonShouldQueueToDispatchSyncRector would wrongly convert those dispatch calls to dispatch_sync .

Example:

- dispatch(function () {
+ dispatch_sync(function () {
    info('test');
});

#206 should fix that.
