Iacuc tests, special review, protocol actions and species & procedures

Lots of tests for IACUC, @wips tags still need to be removed but there are a number of things that need to be reviewed and I assume there will need to be corrections to this pull request. 
This reads very oddly. I think we need to rethink the scenario.

First off, the word "attempt" is inappropriate in this context. Either the code works or it doesn't (and if it doesn't then we get an error).

Secondly, why would a user intentionally "attempt" to add a Special Review item in order to get an error message?

I think the step definition would read better if written like: "creates a Special Review with incorrect data"... or something.
