#15 Caching of question Ids may be problematic

[mrizzo99]

Currently the susrvey persistence service caches question ids. Ran into an issue where question table was not built out and applications was started. Tables were later populated. When the question id was attempted to be retrieved from the cached mapped it failed with a null pointer exception.

java.lang.NullPointerException
