Title: Thumbnailbean dev 4 4

Same as #1257 now on ```dev_4_4```

This PR addresses the issue described in https://trac.openmicroscopy.org.uk/ome/ticket/11072

The problem happens when
* The thumbnail service is recycled.
* The rendering settings are modified, which implies that the thumbnails must be created.
* The thumbnail reloaded using the ```getThumbnail``` method for example.

To test, run
```./build.py -f components/tools/OmeroJava/build.xml test -DTEST=integration/ThumbnailStoreTest```
