Afficher un message d'erreur quand on tente d'ajouter un contact qui n'existe pas

[ggrossetie]

Actuellement, le serveur retourne une 500 et on affiche rien à l'utilisateur :

Something wrong happened during: Adding acquintances => 500, Internal Server Error: {"errors":[{"message":"No user found with this email","locations":[{"line":2,"column":3}],"path":["addAcquintance"]}],"data":null}
askGraphQL @ graphQL.js:35
await in askGraphQL (async)
addAcquintance @ AcquintanceService.js:135

graphQL.js:37 Uncaught (in promise) Error: No user found with this email
    at askGraphQL (graphQL.js:37:11)
    at async AcquintanceAddForm.jsx:19:5

Même chose quand on essaie de s'ajouter soit même à la liste des contacts :

Something wrong happened during: Adding acquintances => 500, Internal Server Error: {"errors":[{"message":"Can not add yourself to acquintance","locations":[{"line":2,"column":3}],"path":["addAcquintance"]}],"data":null}
askGraphQL @ graphQL.js:35

addAcquintance @ AcquintanceService.js:135
