Yes, that still happens.

My change should be down-stream of the dependency solver, so it still
does whatever it did.

The difference is that now when we call 'configure' on each candidate
package, we never pass '--enable-tests' during the 'install' command.

This leads to 'cabal install $pkg --enable-tests' installing test
dependencies but then not building the test suite for the target
package - this is weird, but I'm not sure what we would do with the
test suite after we built it.

If we had a 'auto run test suites on install' feature, we would need
some way to only tweak the config flags of the non-target packages.
But I didn't do that.
