RESTWS-933: Revert RESTWS-901 due to issue saving coded pt attrs

[icrc-fdeniger]

The PR done with RESTWS-901 introduced a regression in the patient registration steps.
If concepts are used for some attributes ( civil status) there are now saved with their uuid in the database ( table person_attribute) and no more with the concept_id.

… (#581)"

This reverts commit cbcf07f.

@k4pran this PR will revert a commit that introduced some side effect on the patient registration.
For sure we can try to fix it correcty but as we deployed it in prod ( and we need the last version for other bugfixes) we propose to revert the commit.

[k4pran]

Yes looks like this reverts the change correctly
