`keybase prove github` in purgatory

```
$ keybase prove github
info: Updated file: /home/steve/.keybase/session.json
Your username on github: elimisteve
...
Check GitHub again now? [Y/n] y
warn: Didn't find the posted proof.

error: in proofd.post_proof (error #703)
steve@steve-dell:~$ keybase prove github
You already have a proved you are elimisteve at github; overwrite? [y/N] n
error: Proof already exists
```

And at https://keybase.io/elimisteve it says I haven't proven that github.com/elimisteve is me. (Thanks for creating all this btw!)

Start by reproducing `keybase prove github` with the reported GitHub account and compare the command output with the profile at https://keybase.io/elimisteve. Trace the proof state from the existing proof error to the missing profile proof; done means the GitHub proof completes and appears on the Keybase profile.
