fix: fix jest timeout in cli cache tests

[mellyeliu]

What changed / motivation ?

In the refactor here #804 we should be wrapping done() in a finally block to prevent the test from hanging if an error is thrown.

Currently, if an assertion fails (e.g., an expect() check fails), the test times out instead of displaying the failure, since done() is never called.

With try/catch/finally:

• Assertions properly fail the test (catch ensures done(err) is called)
• Test always completes, even if an error occurs

This prevents Jest from hanging indefinitely and ensures failures are reported correctly

Testing

Tests pass on main.

In #875, tests no longer timeout, but accurately display the error:

expect(received).toEqual(expected) // deep equality

    - Expected  - 19
    + Received  + 18
