Affiliations of contributors adds noise in Academics Knowledge

[cuent]

Affiliations of contributors adds noise in Academics Knowledge. Some results of authors' affiliations are incorrect when extracting meta data of contributors, and as a consequence, there are other affiliations that the authors is not part of. For example, the author https://academic.microsoft.com/#/detail/1665431955 has other affiliations that his is not part of, as shown in the next figure.

This is affecting the disambiguation process of authors. As a consequence of this, the affiliations of contributors is not been harvested, see AcademicsKnowledgeProvider. Nevertheless, this data might be useful in a near future. As a solution, we could store this data with other property, e.g. uc:affAlt.
