Exception when annotating something after a longer pause

[reckart]

Describe the bug
Sometimes, there is an exception when performing an action in the annotation editor (like annotating something, selecting an annotation or simply reloading) after a longer pause. This seems to happen in particular when recommenders are active in the background.

To Reproduce
Steps to reproduce the behavior:

1. Configure a recommender in the project
2. Set the eviction timeout to a low value cas-storage.cache.idle-cas-eviction-delay=5s
3. Create annotations, delete annotations, select stuff, sometimes waiting longer than 5s in between
4. Eventually, an exception should be thrown that no FS with the given ID could be found in the CAS

Expected behavior
No such exception.

The root of the problem is an upstream issue: apache/uima-uimaj#345

The SelectFS may create temporary annotations which are not tracked in the CAS but which consume IDs. These are not serialized. When reconstructing the IDs from a serialized CAS, the IDs of the non-serialized temporary annotations cannot be accounted for leading to the IDs of the FSes in the loaded CAS to differ from the ones in the original CAS.
