This test could sometimes fail because of a lack of free contiguous pages in the file system. Fix this by removing the created files at the end of each test. Besides, the test files do not have to be removed at the beginning of each test since the file system is initially formatted. Signed-off-by: Benoît Thébaudeau <benoit.thebaudeau.dev@gmail.com>
