This fixes the testsuite in master.
For the Redis storage, the test failure seems to come from a bad resolution when merging 2.1 into master.

I still have some failing tests in master locally:

- some tests with the incremental output tests in the Process component
- a timing test for the Stopwatch component (but passing when running only the Stopwatch tests)
- some mock expectations in the Form component.

However, all these tests are passing on Travis so it looks weird.
