remove duplicate entry for Rep. David Levy Yulee (1841-1861)

This guy had two entries probably because he had also previously had two Bioguide IDs assigned. The entries had the same bioguide ID listed but different GovTrack IDs.

The entry I'm removing had `bioguide_previous` and `other_names` (1d0416d6582262a846858bcc98ee017c649a97b0) fields filled in, and I'm now copying them into the other entry.

The entry I'm removing had been assigned the unique GovTrack ID 406767, so that ID is now disappearing. It was also missing some terms that are present on the entry that I'm keeping.
