### Please describe the problem.
On the first run it seems "Open Webapp" always use the URL used to configure a new repo.

### What steps will reproduce the problem?
I'm using a /sdcard/DCIM annex.

1. close the tabs in the git annex terminal to close git annex
2. force close the application in the settings and delete data (not sure if it's needed)
3. delete /sdcard/DCIM/.git/ and /sdcard/git-annex.home/ (I'm not sure I'm deleting everything, maybe I missed some dirs)
4. start git annex

(WebApp opens and ask to create a repo) see: [http://i.imgur.com/v0EUuir.png](http://i.imgur.com/v0EUuir.png)

5. Click "Make Camera Repository"

(WebApp scans and commits the files) see: [http://i.imgur.com/97rYfXa.png](http://i.imgur.com/97rYfXa.png) (note that the port changed)

6. Return to the terminal. see: [http://i.imgur.com/edL5and.png](http://i.imgur.com/edL5and.png)
7. Open WebApp using the menu

(Git annex opens the URL to configure a new repo (the webapp is still accessible with the other url). see: [http://i.imgur.com/T8A5NTD.png](http://i.imgur.com/T8A5NTD.png)

If I close and reopen the terminal, the good url is used when I use "open webapp"
