internal_server_error:_unknown_UUID_on_webapp.mdwn

### Please describe the problem.

I am having trouble using the webapp with a setup I did on the commandline that was working fine.

I have two machines: one, a server called `marcos`, is available on the internetz and I cloned a repo from there into `markov`, a workstation that is hidden behind a NAT connexion (so I can't add it as a remote).

It seems that because the remote is not locally available as a git remote, the webapp is freaking out because it doesn't recognize `markov` as a proper remote.

### What steps will reproduce the problem?

1. setup git annex locally (on `marcos`) in a repository (probably `git annex init; git annex direct; git annex add .` i somewhat followed [[tips/Git_annex_and_Calibre/]])
2. `git clone` that repo on a remote, unaccessible (NAT'd) server (`markov`)
3. start doing some git annex get, get tired, run the web app on `markov`
4. let that run over there, go back to `marcos`
5. be curious about what is going on on `markov`, run the webapp and enter the path to the repository created in step one when prompted (it's the first time i run the webapp)
6. it starts up fine, but doesn't seem to detect `markov`, marking transfers as going to the remote named `unknown`
7. click on the `unknown` link, crash
8. go back to the dashboard, crash

From there on, the webapp is pretty much crashed, starting it from scratch asks me if i want to create a git annex repo.

### What version of git-annex are you using? On what operating system?

4.20130921-gd4739c5 compiled and installed by hand on debian wheezy.

### Please provide any additional information below.
