[gnome-contacts] Don't restrict RowData.details to the generic type "string"

    Don't restrict RowData.details to the generic type "string"
    
    This allows AbstractFieldDetails<G> based values to be assigned,
    like PostalAddressFieldDetails.
    
    Fixes a build-failure with vala 0.35+ due to stricter type-checking.
