Command line error: UID mismatch null

Trying to perform any command via the command line results in the following error:
`error: UID mismatch null != 5e9faa7093e4e5d90402ad6faab1ef00 in tree for kevinvandenberge`

Can't be sure when the issue started, but I just tried keybase today (2016-7-19) and was slapped with this error.

example:

```
kvb::{~} -> keybase version
keybase (keybase.io CLI) v0.8.25
- node.js v0.10.30
- gpg (GnuPG/MacGPG2) 2.0.30
- libgcrypt 1.7.0
Identifies as: 'keybase.io node.js client v0.8.25 darwin'
```

Start by reproducing the failure with `keybase -d list-sigs` using the reported CLI version, then inspect the local config, session, signature-chain loading, and `merkle/path` request shown in the debug output. Done means the command completes without reporting a UID mismatch for the user.
