Subject: [PATCH] Fix failing fills_and_removes_from_window test

As the tests are run concurrently, the directory might already
exist, so just ignore the failure.

Fixes the following error when running the tests:

---- window::tests::fills_and_removes_from_window stdout ----
thread 'window::tests::fills_and_removes_from_window' panicked at 'called `Result::unwrap()` on an `Err` value: Os { code: 17, kind: AlreadyExists, message: "File exists" }', src/window.rs:194:38
