Markers are not visible. #29

Looks like non clustered markers are not drawing after move via camera 
animation.

Steps:
- initial state is zoomed;
- see 01_initial_state;
- start to move camera via next code 
CameraUpdate cameraUpdate = 
CameraUpdateFactory.newLatLngBounds(builder.build(), 20);
- see 02_after_camera_animation, it's wrong;
- try to zoom out via map button "-" markers clustering, but single still 
missing;
- see 03_after_zoom_out, it's wrong;
- scroll (drug) map and missing single markers will apear;
- see 04_after_scroll, it's correct.

Hey Igor,

This looks serious. Which version of the library are you using?

Can you provide a more complete code to reproduce this issue?

I used latest version from master branch.
I attached project with issue. It is based on demo, quick and dirty 
implementation, sorry :).

Steps to reproduce.
- start app and wait until it will be zoomed to Warsaw (1.png);
- click on Issue 29 and see markers (2.png);
- zoom out via maps "-" button (3.png);
- scroll horizontal/vertical to see missed marker (4.png);

Lets me know if you need something else.

Got it reproduced. Clusters were not refreshed when using 
addMarkersDynamically, when they were not initially not on screen and they 
didn't join after zoom out.

For a quick fix go to GridClusteringStrategy.joinClusters and replace

            if (clusterList.size() == 1) {
                ClusterMarker cluster = clusterList.get(0);
                newClusters.put(key, cluster);
            } else {

with

            if (clusterList.size() == 1) {
                ClusterMarker cluster = clusterList.get(0);
                newClusters.put(key, cluster);
                if (!addMarkersDynamically || isPositionInVisibleClusters(clusterList.get(0).getMarkersInternal().get(0).getPosition())) {
                    refresh(cluster);
                }
            } else {

Similar code will be popped in for the next release.

Have to check the same for zoom in and no-split clusters.

Thanks for the report.
