Capitalization of Key

When requesting portfolio items, the key used in the rest response is odd. The
existing code to munge it was not preserving necessary capitalization, and so
get requests using entity-types of PortfolioItem/MarketRequirement,
PortfolioItem/ProductRequirement, and PortfolioItem/ReleaseRequirement were
failing.
