Support for tasty test dependencies (Non-exhaustive pattern match warnings with tasty-1.4.1)

[sjakobi]

I simply noticed these in the build log and wondered whether they would pose a problem:

Test/Tasty/Silver/Filter.hs:114:9: warning: [-Wincomplete-patterns]
    Pattern match(es) are non-exhaustive
    In an equation for ‘filter'’:
        Patterns not matched:
            [] (After _ _ _)
            (_:_) (After _ _ _)
    |

    |         ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^...

Hm, looks like tasty-silver does not support test dependencies as introduced in UnkindPartition/tasty@6506bef / UnkindPartition/tasty#48 . As long as you are not using this tasty feature you should be perfectly fine.

I guess fixing the test filtering might not be so simple, as I guess if a test ends up in the final set of tests to run it should also include all transitive dependencies. I don't think I will get around to fix this in the near future, but if anybody wants to give it a go feel free to open a PR.
