rwlock conflict with fastapi test client

[M03ED]

im using rwlock on marzban project.
we have some test case with fastapi test client to make sure everything is ok
when we need to access lock in multiple request we get this error

self = <aiorwlock._RWLockCore object at 0x7f0d7471a570>

    def _get_loop(self) -> asyncio.AbstractEventLoop:
        """
        From: https://github.com/python/cpython/blob/3.12/Lib/asyncio/mixins.py
        """

        loop = asyncio.get_event_loop()

        if self._loop is None:
            with _global_lock:
                if self._loop is None:
                    self._loop = loop
        if loop is not self._loop:
>           raise RuntimeError(f'{self!r} is bound to a different event loop')
E           RuntimeError: <aiorwlock._RWLockCore object at 0x7f0d7471a570> is bound to a different event loop

.venv/lib/python3.12/site-packages/aiorwlock/__init__.py:54: RuntimeError

i replaced aiorwlock with asyncio.lock temporary and problem solved commit

If the loop is getting recreated for each test, then the places where the lock is being used should probably also be done per test (i.e. it shouldn't outlive the loop).

However, if asyncio.Lock is no longer tied to a specific loop, we can probably adopt the same change here, if someone wants to investigate that change.
