* Caches are compared as files now. It is a more robust approach
than comparing strings with dumped contents. E.g previous test
ignored differences in keys ordering, because dumping caches to string
was added for comparing caches after incremental and non-incremental builds,
which cannot be compared without sorting keys (see KT-32674).
* Calling setUp/tearDown twice within the same test instance was
relatively hacky and fragile. Also it complicated adding new test cases.
