Feat/186 experiment refactor

Updated result to results to be able to save multiple results and fixed agreedNDA so the property is up to date even when you logout and login again.

Removed the algorithm name  from experimentDTO so it wont be required or will return algorithm name twice but the algorithm name still exists in the database to help with the filtering on the GET /experiments request.

Added badrequest in case  algorithm type is null and fix the convertion of the json that exareme provides to a list of results.

Remove article from database.Made GET /experiments return only my experiments or the shared and wont print the result of the experiment.
