Remove observation identifier from local cache:
- because it can result in a big cache file if each observation has an observation identifier, e.g. 150000 observations with identifier ~ 15 MB cache file.
- only used by DeleteObservation to check if the requested identifier is valid. Now the database is queried and the invalid parameter exception is thrown if no observation was found.
