Implement a permute_for_extension helper.

Use it for all of the 'simple' extension permutations.
It basically permutes all tests in the current module, by setting TestCase.module.
Which works well for most of our extension tests. Some had more advanced
handling of permutations (extra permutations, custom vars, etc.)
