Session trace not cleaned up causing "tracing.stop" error in subsequent tests with Playwright

#### What are you trying to achieve?

I'm trying to run multiple test scenarios where the first scenario uses `session()` with Playwright helper and trace enabled. Both tests should pass without errors.

#### What do you get instead?

After the second test completes successfully, CodeceptJS throws an error:
```
Error: tracing.stop: Target page, context or browser has been closed
```

The session created in the first test is not properly cleaned up, and when the second test finishes, CodeceptJS attempts to save the trace for the old session that no longer exists.

First test with session
Scenario()
I am on page "/"
user1: I am on page "/"
user1: I see "Example Domain"
I see "Example Domain"
✓ OK in 4197ms

Second test - should fail with trace error
Scenario()
I am on page "/"
I see "Example Domain"
✓ OK in 630ms

Error: tracing.stop: Target page, context or browser has been closed

OK | 2 passed // 6s

Scenario('First test with session', ({ I }) => {
I.amOnPage('/');

session('user1', () => {
I.amOnPage('/');
I.see('Example Domain');
});

I.see('Example Domain');
});

Scenario('Second test - should fail with trace error', ({ I }) => {
I.amOnPage('/');
I.see('Example Domain');
});
```

### Details

* CodeceptJS version: 3.7.6
* NodeJS Version: v20+ (any recent version)
* Operating System: Windows / Linux / macOS (reproduced on all)
* Playwright version: 1.40.0
* Configuration file:

```js
exports.config = {
tests: './*_test.js',
output: './output',
helpers: {
Playwright: {
url: 'https://example.com',
show: false,
browser: 'chromium',
trace: true,
keepTraceForPassedTests: true
}
},
bootstrap: null,
mocha: {},
name: 'codeceptjs-session-bug'
}
```

### Additional context

The issue appears when:
- Multiple scenarios are run in sequence
- Trace is enabled (especially with `keepTraceForPassedTests: true`)
- One or more scenarios use `session()` helper

The session context is closed after the first scenario ends, but CodeceptJS still tries to stop tracing for it when the next scenario completes.
