[BUG] Invalid swagger path is generated
## Information

- **Version:** 6.123.1

Invalid swagger API path is generated when mounting controller with same path as defined in config.

## Example

index.ts
```ts
...
const importConfig = {
    mount: {  '/tests/': [`some-path\\**\\controllers\\**\\**.[jt]s`] },
    imports: [ `some-path\\**\\**.[jt]s` ]
};
const scannedProviders = await importProviders(importConfig);
...
```

controller.ts
```ts
...
@Name('test')
@Controller('/test')
export class CustomerController {
    @Get('/')
    testFn(): string {
        return 'it works';
    }
}
...
```

For above configuration, swagger path is generated as following:
```json
{
    "paths": {
        "/s/test/test": {
            "get": {}
        }
    }
}
```

API is still accessible as it should be on path '/tests/test'.
