Fix two tests that depended on the platform and on the test order

DirectoryResultCacheValueExtensionTest built the key from __DIR__ . '/data',
which a round trip through the result cache turns into backslashes on
Windows. ValueDependencyCollector normalizes the directory before it creates
the key, so the test now does that too.

ValueDependencyCollectorTest counted all calls of the extension, which the
container shares with the other tests in the class. It now counts the calls
the test itself makes.
