Remove unneeded context values new (#771)

Remove values from metadata[["context"]] if there are neither descriptions nor a find -> value replacement. The traits.build workflow now automatically reads in the list of unique values from the specified column if no values are given.  (Possible following the completion of traitecoevo/traits.build#15)
