Do not build NAME_LOOKUP from phonetic names

This prevents aggregation by phonetic name

Note: if a contact only has a phonetic name (i.e. without any non-phonetic name components), then
its display name is set from the phonetic name.  This CL does *not* prevent phonetic-name-based
display names getting into NAME_LOOKUP, meaning if two contacts have no names but the same phonetic
name, then they *will* still be aggregated.  But this shouldn't be an issue since what was an issue
was "aggregating two contacts with *different* names with the same phonetic name".
