Contacts/OrgCard: improve otherAttributes layout

[bernhardreiter]

Currently (e4f203fb5a01bcf05f8c01bec53abc3ee31de1e6) the order how some attributes is undefined as they are iterated over the keys of an object like

       <div v-for="(value, key) in otherAttributes">
            <strong>{{ key }}</strong>: {{ value }}
        </div>

For a better user experience the order should be the same for all objects.

Technical ideas:

• use an array to sorts the keys in and loop over that
• manually hardcode each attribute
