Fixed badly handled fundamental types in json_deserialize_pspec().

This patch fixes json_deserialize_pspec() to return FALSE when
failing to deserialize some properties. Consequently the patch
ensures we get the intended warnings when failing to deserialize
pspecs for some fundamental types:
  Failed to deserialize property "foo" of type "int" on object "bar"
