Not existing attribute in Horizon2020 view

[ClaraRosalie]

Describe the bug
The attribute project/legal_aspects/security_measures is assigned to the question What provisions are in place for data security (including data recovery as well as secure storage and transfer of sensitive data)? in the Horizon2020 view but does not exist in any catalog. We've had the same issue with the ERC view and solved it by replacing the attribute with another one project/dataset/data_security/security_measures. Unfortunately this attribute is already part of the Horizon2020 view so it cannot be used.

We have to find another matching attribute for the question What provisions are in place for data security (including data recovery as well as secure storage and transfer of sensitive data)?.
