ArrayStoreException on EntityList

[kevinpeterson]

When constructing a List directory, the expected resource should be a EntityListEntry object, not a EntityDescription object. Because this is done via reflection, we won't catch this a compile time, so we'll probably need some finer-grained unit tests for these list=true operations.

Test case for one that is currently failing:
This works:
http://vmware_win_7:8080/codesystem/UMLS_SemNet/version/3.2/entities?list=false

This breaks:
http://vmware_win_7:8080/codesystem/UMLS_SemNet/version/3.2/entities?list=true

hmm, no idea how I closed this... didn't intend to.
