[Views integration] Remove unnecessary json_encode and json_decode calls
There are some unnecessary calls to json_encode()
and json_decode()
for the params
property of CMRFDataset
entities. This MR makes the JSON be parsed in the constructor and removes the JSON-coding calls where they are not needed anymore.
Also, the method for retrieving all datasets is being simplyfied with this MR, since that was closely coupled with the JSON thing.
