Resolve "ISC : Show user Sector instead of Unit when creating an annotation: Client adaptation"

Closes #6 (closed) From the annotate server, a list of the "longest" sectors of the current user is transmitted. In the "userInfo.entities" structure. In the "entities" array, the name of the organization and the sector are passed as pairs. Perhaps I misunderstood what a Sector and a Unit are. It may be necessary to use the Sector first, and after sending the Organization (unit). This can be used in the converter-side by simply selecting (if there is more than one) the appropriate one. But it's all weird. I assumed that the username and sector should be remembered along with the annotation and not depend on the current user or the fact that the creator user is no more. And the choice of the user sector is rather strange. It's amazing that this is working so far. Therefore, check whether it works so far, as you expected?!
