test: Run tests in unique directorywip/oholy/test-unique-dir

The tests currently create various files and directories with generic names
and manipulate with them directly in the `/tmp` directory. The tests also
remove all files in `/tmp` with the generic prefixes like `move`, `copy`,
etc. This can simply cause test suite failures if files with such names
already exist in the `/tmp` directory. Also, the test suite can easily remove
files created by other applications. Let's always create an unique directory
in `/tmp` for tests to fix the mentioned problems...
