Show at least one anonymous user in the contribution card

[cdparra]

Currently, if no author exists, it shows Anonymous, even if there is a non-member-author. If there is a non-memmber-author with a name, show that name with Anonymous.

Still an issue, looking at the code at:

appcivist-pb-client/app/v2/partials/directives/contribution-card.html

Line 27 in 9c34b27

<span ng-if="!contribution.creator">{{'ANONYMOUS' | translate}}</span>
