Revert TestCaseInSubDir parts of "downgradedatabase: blackbox test"

This reverts part of commit 74d15c9bf76f0a2fb5fa7b7b1d80971d10c4fe45.

TestCaseInSubDir should not have been modified in this way, instead
the downgradedatabase test should have removed the files it created
specifically (this is part of the test, it shows the right files were
created).
