Problem/Motivation

_mailchimp_lists_subscription_has_changed() uses the output of MailchimpListsSubscription::getInterestGroups() unconditionally as input for a foreach loop. MailchimpListsSubscription::getInterestGroups() however can return NULL.

Proposed resolution

Make MailchimpListsSubscription::getInterestGroups() to always return an array

API changes

MailchimpListsSubscription::getInterestGroups() now returns an empty array instead of NULL if no interest groups were saved for a subscription.

Data model changes

None
