SynchronizationRequests can be created with non-unique ids

In my use-case, I create a list of synchronization requests (for my 14 workspaces). These happen sequentially, but evidently too quickly, as the ID for each request is the same. This makes it impossible to get information about a particular request from the synchronization manager. 

Steps to reproduce

1. For loop over the below method, to create requests: 

   private SynchronizationRequest createSynchronizationRequest(String url, String workspace) {
     SynchronizationRequest req = new SynchronizationRequest();
     req.setUrl(url);
     req.setWorkspace(workspace);
     req.setFromPath("/");
     req.setToPath("/");
     return req;
   }
   

1.  note that all the requests will have the same id: `req.getIdentifier()`

Expected results

Requests should have unique IDs, so that they can be queried by ID later. 

Actual results

Requests have the same identifier. 

Workaround

I manually appended the workspace to the identifier: 

private SynchronizationRequest createSynchronizationRequest(String url, String workspace) {
  SynchronizationRequest req = new SynchronizationRequest();
// THIS LINE  
  req.setIdentifier(generateNewSyncId(workspace));
// ^^^^^^^
  req.setUrl(url);
  req.setWorkspace(workspace);
  req.setFromPath(ROOT_PATH);
  req.setToPath(ROOT_PATH);
  
  return req;
}

The generateNewSyncId() method just creates a string from the date + the workspace.
