proven identities are gone

I have proven my twitter and github identity, which worked, but now when I view my profile page (https://keybase.io/rpirringer) now the initial "prove my twitter/github identity" links are shown. Also my picture is gone.

When I try to prove the identity again via command line I get this:

```
# keybase prove github renep
info: Updated file: /Users/rene/.keybase/session.json
info: Creating temporary keyring dir: /Users/rene/.keybase/tmp_keyrings
You already have proven you are renep at github; overwrite? [y/N] N
error: Proof already exists
#
```

What I have done is that I have updated my key with `keybase push --update` (because I have added additional email addresses to the key)

Start by reproducing the missing proofs and picture on the linked profile page, then compare that with the `keybase prove github renep` and `keybase push --update` flows described in the report. Done means previously proven identities and the profile picture are visible again, while re-proving does not incorrectly report that the proof already exists.
