Fix middleware

In server\core\auth\jwt\middleware.py must be removed the following condition with access_token
From:
```python
def resolve(self, next, root, info, **kwargs): # noqa: WPS125
"""Middleware resolver."""
context = info.context
access_token = utils.get_access_token_by_request(context)

if access_token:
context.user = SimpleLazyObject(lambda: get_user(context))
context.refresh_token = SimpleLazyObject(lambda: get_refresh_token(context))
```
To:
```python
def resolve(self, next, root, info, **kwargs): # noqa: WPS125
"""Middleware resolver."""
context = info.context

context.user = SimpleLazyObject(lambda: get_user(context))
context.refresh_token = SimpleLazyObject(lambda: get_refresh_token(context))
```
Because context saves user and refresh_token statements in next requests.

Open server/core/auth/jwt/middleware.py and inspect the resolve method and its use of context, get_user, and get_refresh_token. Confirm the access-token condition is the source of the persistence issue, then verify that the middleware assigns the expected context values on subsequent requests.
