Change the default naming of test files to: `"test/{{sanitized}}/core_test.clj"`.
This is to be compatible with both Leiningen naming and clojure-test-mode.
`clojure-jump-between-tests-and-code` should work again.
Merge pull request #41 from bonega/default-testname-cleanup

Testfiles default name should be consistent with lein.
