Fix unstable UtilAllTest#testCalculateFileSizeInPath on Windows

On my Windows laptop, UtilAllTest#testCalculateFileSizeInPath is
unstable, presumably due to leftovers from previous runs that were not
properly cleanup up.

Converting the test to use a proper TemporaryFolder @rule like other
tests that rely on the filesystem instead of trying to implement the
cleanup logic in the test itself seems to solve this.

Closes #7418
