Print number of tests when no failures

[yaitskov]

Hi,

I found current behavior distracting, because when all specified tests pass - it is not clear whether it is really green or I just made a typo in a regex pattern for test names I would like to run and run zero tests.

cabal test  --test-options "-p /Unuset/"

Running 1 test suites...
Test suite spec: RUNNING...
Test suite spec: PASS
Test suite logged to:
/home/dan/pro/dist-newstyle/build/x86_64-linux/ghc-8.10.6/napkin-0.3.8/t/spec/test/pro-0.3.8-spec.log
1 of 1 test suites (1 of 1 test cases) passed.

It's not up to tasty; cabal suppresses successful test output unless invoked as

cabal test --test-show-details=direct
