Broken PolicyBrain prior-run links

[MattHJensen]

It appears that a recent PolicyBrain update broke old CCC links. I should be able to go to ospc.org/ccc/800, for example, and see results, but instead I get a 500 internal server error. Similarly, I should be able to go to http://www.ospc.org/ccc/edit/800/ and see the parameter changes that resulted in ospc.org/ccc/800.

We do not need to ensure that users can re-run old simulations, but they should be able to see their results, the inputs that generated, and the version of PolicyBrain that they used. With this information and some work, it should be possible to replicate analyses locally.

Whether or not it is possible to fix this problem now, we should have some tests that protect links in the future and to document that this is a PolicyBrain requirement.

@MattHJensen It looks like the edit page is working fine. I'm not sure what's going on with the results page. I'll look into this.

It looks like this capability works back to run 877 which occurred on the same day as PolicyBrain release 1.0.3. This was the release where we started using the bokeh plot for the CCC. B-Tax had to be updated in order to return the required data for this plot. Thus, when we try to load an earlier CCC run, we are unable to parse the results.

Note that the user can got to the edit page, http://www.ospc.org/ccc/edit/800/, and re-run the model.
