Correction of JsonPrinter output for metadatablock api calls

+This pull request fixes an issue in the JsonPrinter class so that there are no duplicated entries in the JSON metadata or ommitted metadata properties. After the fix is applied the /api/metadatablocks/ endpoint should return correct JSON.

 v6.4
 ----
 
+- /api/metadatablocks is now returning no duplicated metadata properties and does not ommit metadata properties when called. The JsonPrinter class output is fixed.
 - **/api/datasets/$dataset-id/modifyRegistration**: Changed from GET to POST
 - **/api/datasets/modifyRegistrationPIDMetadataAll**: Changed from GET to POST
 - **/api/datasets/{identifier}/links**: The GET endpoint returns a list of Dataverses linked to the given Dataset. The format of the response has changes for v6.4 making it backward incompatible.
