cabal test seems broken with cabal-install HEAD

[Johan Tibell]

Hi,

I tried to use cabal-install from today's HEAD but it doesn't seem to
pick up test-suites anymore:

$ ../cabal/cabal-install/dist/build/cabal/cabal clean

$ ../cabal/cabal-install/dist/build/cabal/cabal configure
--enable-tests --enable-library-coverage

$ ../cabal/cabal-install/dist/build/cabal/cabal test
--test-option=--plain --test-option=--jxml=dist/unit-tests.xml
cabal: No test suites enabled. Did you remember to configure with
'--enable-tests'?

This is using the hashable package from https://github.com/tibbe/hashable
