recentmodel: add CMs which have a PersonPlaceholder
recentmodel: add CMs which have a PersonPlaceholder

Otherwise calls associated with these ContactMethods will
not show up in the RecentModel, since PersonPlaceholders are not
part of ther PersonModel.

This patch also checks the list of CMs in the RecentModel in case the
Person associated with a CM is not found (as it means that it is a
PersonPlaceholder)
