Fix hard-coded edge regex in test-all
Fix hard-coded edge regex in test-all

Fix https://github.com/juxt/edge/issues/80

The edge regex would only test edge namespaces.  Using a ".*" equivalent
regex results clojure.test outputting "noise" for 0 tests in random
non-test namespaces.

This implementation uses the same filter that clojure.test uses to
find tests in a namespace, and only passes that list of namespaces to
clojure.test.
