Fix problem with user mailaddresses when sending a newsletter

Dit lost hoogstwaarschijnlijk #236 op. Aangezien user 'adridg' met de status 'erelid' geen e-mailadres heeft en ik er geen rekening mee had gehouden dat dit mogelijk kon zijn. E-mailadres is blijkbaar ook niet verplicht.

Verklaart alleen nog niet waarom t bestuur wel de mail heeft ontvangen, waarschijnlijk omdat ze onder 'engels' vielen?

The previous version did not take into account that
people could have multiple memberships that did not overlap.
