Always show family when displaying upper taxon levels, omit genus #421
Description
Currently we show the 2 taxon levels above species. Since moths commonly have tribe or subfamily, the family is usually never visible. Also the genus is redundant since it is part of the species name. The family is one of the most helpful taxon levels.
This likely depends on #264, because there are already too many SQL joins when populating the upper taxon levels for each species in an API response.
Here is a new design where the first element is always the Family, followed by a "|" symbol. Then the last 2 levels are dynamic (the next upper 2 levels that are available after genus, but before family)
