weare: Console chrome fails to display firstname lastname from Github

**Migration of dbc/shazzam ticket #85** [link] (https://github.com/Devbootcamp/shazzam/issues/85#issuecomment-53462627)

Students log in with weare. They expect the console to display firstname lastname of the two logged in users. The names are not appearing. 

In the past we've had issues with the Github rate limit apparently due to us using un-authenticated requests to the API. In particular, this blows up every day one as students try weare for the first time. This causes much sadness, as the students assume either they are doing it wrong, or DBC systems don't work. 

In this case, the does-not-display-name bug have persisted for two students into day two. User codenado is one of these. 

Oh, and here's our ratelimit again. I guess this is that issue.

I would normally treat UI chrome as low priority except this is literally the first thing students do on a DBC workstation, and it breaks every time. I'd ask us to fix the ratelimit issue or take the ~~usernames~~ names off the workstations. 
```sh
"$name" || name=`get_field_from_json "$user_json" login`
```
would also work
